[Question]
  [
In 2014, demoscener Jakub 'Ilmenit' Debski [released](http://www.pouet.net/prod.php?which=62917) a 250-byte(1) procedural graphics demo for the [Atari XL](https://en.wikipedia.org/wiki/Atari_8-bit_family) called *Mona*. It's drawing the following picture(2):
[![mona](https://i.stack.imgur.com/3aZ5s.png)](https://i.stack.imgur.com/3aZ5s.png)
Your task is to generate the exact same picture, using the language of your choice.
---
(1) Breakdown: 136 bytes of data + 114 bytes of code.  
(2) The original picture is 128x96. The above version was magnified to 256x192. A few pixels differ from the original, but this is the expected output with the pseudo-code described in this challenge.
## How?
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"). Although you're authorized to use any method, best results will most probably be achieved by using the original algorithm which is described below.
**NB**: This paragraph is *not* a specification but rather a general description. Please refer to the pseudo-code and the reference implementation for the details of the algorithm.
The image is made of 64 pseudo-random brush strokes ([see this video](https://youtu.be/0NHaFS9YJBE)), cycling through the following colors (in RRGGBB hexadecimal format):
```
COLOR = [ 0xFFE289, 0xE99E45, 0xA55A00, 0x000000 ]
```
The background is initially filled with the 4th color (black). Each stroke is shorter than the previous one.
The pseudo-random generator is using a Linear-Feedback Shift Register (LFSR) on a 32-bit integer initially set to `0x7EC80000` and XOR'ed with `0x04C11DB7`.
Each stroke is initialized with a 16-bit value which overwrites the least significant bytes of the seed:
```
BRUSH = [
  0x030A, 0x37BE, 0x2F9B, 0x072B, 0x0E3C, 0xF59B, 0x8A91, 0x1B0B,
  0x0EBD, 0x9378, 0xB83E, 0xB05A, 0x70B5, 0x0280, 0xD0B1, 0x9CD2,
  0x2093, 0x209C, 0x3D11, 0x26D6, 0xDF19, 0x97F5, 0x90A3, 0xA347,
  0x8AF7, 0x0859, 0x29AD, 0xA32C, 0x7DFC, 0x0D7D, 0xD57A, 0x3051,
  0xD431, 0x542B, 0xB242, 0xB114, 0x8A96, 0x2914, 0xB0F1, 0x532C,
  0x0413, 0x0A09, 0x3EBB, 0xE916, 0x1877, 0xB8E2, 0xAC72, 0x80C7,
  0x5240, 0x8D3C, 0x3EAF, 0xAD63, 0x1E14, 0xB23D, 0x238F, 0xC07B,
  0xAF9D, 0x312E, 0x96CE, 0x25A7, 0x9E37, 0x2C44, 0x2BB9, 0x2139
];
```
These values are also used to set the new position ***(bx, by)*** of the brush at the beginning of the stroke: ***bx*** is given by the least significant byte and ***by*** is given by the most significant byte.
The direction of the stroke is given by bits #1 and #7 of the seed. (See the SWITCH statement in the pseudo-code.)
## Pseudo-code
Below is the algorithm in pseudo-code, assuming 0-indexed arrays, where `AND`, `OR` and `XOR` mean bitwise operations.
```
seed = 0x7EC80000
dir = 0x00
FOR part = 0 TO 63
  word = BRUSH[part]
  seed = (seed AND 0xFFFF0000) OR word
  bx = word AND 0xFF
  by = (word >> 8) AND 0xFF
  FOR len = 0 TO (64 - part) * 32 - 1
    carry = seed AND 0x80000000
    seed = (seed << 1) AND 0xFFFFFFFF
    IF carry
      seed = seed XOR 0x04C11DB7
      dir = seed AND 0xFF
    ENDIF
    SWITCH dir AND 0x82
      CASE 0x00:
        by = (by + 1) AND 0x7F
      ENDCASE
      CASE 0x02:
        bx = (bx + 1) AND 0x7F
      ENDCASE
      CASE 0x80:
        by = (by - 1) AND 0x7F
      ENDCASE
      CASE 0x82:
        bx = (bx - 1) AND 0x7F
      ENDCASE
    ENDSWITCH
    drawPixel(bx, by, COLOR[part AND 3])
  ENDFOR
ENDFOR
```
## Reference implementation
Below is an ungolfed reference implementation in JavaScript.
```
const SEED    = 0x7EC80000,
      XOR_MSK = 0x04C11DB7,
      COLOR   = [

        0xAF9D, 0x312E, 0x96CE, 0x25A7, 0x9E37, 0x2C44, 0x2BB9, 0x2139
      ];
var ctx = document.getElementById('output').getContext('2d'),
    seed = SEED,

  seed = (seed & 0xffff0000) | word;
  bx = word & 0xff;
  by = (word >> 8) & 0xff;
  ctx.fillStyle = COLOR[part & 3];
  for(len = 0; len < (64 - part) * 32; len++) {
    carry = seed & 0x80000000;
    seed <<= 1;
    if(carry) {
      seed ^= XOR_MSK;

You can also [see an animated version here](https://repl.it/JrzB/0).
## Clarification and rules
* The output must be cropped to 128x96, even though the algorithm draws outside this area.
* If your language/platform is not able to output the exact colors described above, you must use colors that are as close as possible.
* Should you decide to use an alternate method, you still must generate the exact same output.
* Just in case: submitting the original 6502 assembly code or any slightly edited version is not allowed.
* Can you beat 250 bytes? Happy drawing!

# Excel VBA 32-Bit, ~~1011~~ 407 + 128 = 535 Bytes
*Revision 69; ŒîScore= \$-476\$ Bytes*
A full VBA subroutine, and helper file ,`"B"`, that takes no input and outputs the *Mona Lisa* to the `ActiveSheet` object on the range `[A1:DX96]`. This solution starts from the Previous Approach, shown below, and uses old school file relies VBA's `Open` and `Get` commands to pull the raw 16-bit values from the file, byte by byte.
This approach of using `Open`, `Put`, `Get`, and `Close` for handling raw data I/O dates back at least as far as 1981 with [IBM's Disk Basic and Advanced Basic](https://archive.org/details/IBMBASICAV1.10Manual/page/n337/mode/2up), authored by Microsoft. It is possible that this style of IO goes back even earlier, possibly being defined in 'ANSI X3.60-1978 "For Minimal BASIC"', however this standard is not freely available to the public.
This style of handling raw data I/O was inherited by many Microsoft authored BASIC dialects, including GW-BASIC, QuickBASIC, Visual Basic, and Visual Basic for Applications. Notably, this style of raw data I/O was not included in VB.Net.
 *Note: This solution has been restricted to 32-Bit versions of Excel VBA as [`^` is the `LongLong` type literal](https://codegolf.stackexchange.com/a/143645/61846) in 64-Bit versions*

## Previous Approach, 618 Bytes
An immediate window function that takes no input and outputs the *Mona Lisa* to the `ActiveSheet` object on the range `[A1:DX96]`.

This is a further golfed-down version of [CCB60](https://codegolf.stackexchange.com/users/70031/ccb60)'s Python translation of the reference implementation. I originally used a large hex number to represent the brush of the algorithm, but I later realized that my unfounded assumption that a Unicode string representation wouldn't work in Python was false.
I originally thought my byte count was significantly lower, but as [ASCII-only](https://codegolf.stackexchange.com/users/39244/ascii-only) pointed out, I didn't remember to count the Unicode characters as more than one byte.

There are a number of issues that make this a challenging problem in Befunge:
1. Befunge has only got 2000 bytes of memory to work with (and that includes the source code), so there is no way we can render the entire image into memory before outputting it. The way I work around this is by repeatedly running the algorithm 96 times, once for each line. Each run stores just the pixels that are needed for the current line, which are then output at the end of the run. This allows us to get by with a pixel buffer of just 128 bytes.
2. Befunge has no bit operations whatsoever. Many of the `AND` operations can simply be emulated with a modulo operator (e.g. `a AND 0x7F` can be replaced with `a % 0x80`). However, the `XOR` requires some rather complicated bit manipulation, which we have to deal with one byte at a time, using a set of custom formulas hardcoded to handle the four bytes we need. For example, to calculate `a XOR 0xC1`, we use the formula: `a + 0xC1 - (a/64%4*64 + a%2)*2`
3. While not a limitation of Befunge per se, the interface on TIO is incapable of handling extended ASCII characters in the source, which would have been the easiest way to store the brush and colour tables. I work around this by generating those tables as a list of numbers on the stack, then have a little initialisation loop that copies the values from the stack to memory. A significant chunk of my time was spent golfing this table, which takes up the first five and half lines of code.
Unfortunately, despite all my effort to make the code compatible with TIO, and my choice of a file format that could be extracted from TIO ([PPM](https://en.wikipedia.org/wiki/Netpbm_format)), it's just too slow to complete within the 60 second time limit (running the algorithm 96 times probably doesn't help). But since it generates the image line by line, you should still get enough of the output to recover nearly half the image.

A straight forward copy of the pseudo code with some golfing added in. There is still a lot that can be golfed but I wanted to post my answer to get the ball rolling.

# Python 2.7; ~~880~~ 876 bytes total (including data)
-4 bytes to 876 thanks to ZacharyT. (My python interpreter did not like his suggestion to drop the spaces between the 80s and else).
Taylor Scott's suggestion to put the brush into Base 10 is excellent, but notjagan (in a comment) took his suggestion one step further, using python's extended integer format in hex. notjagan's answer is in Python 3, and is such an improvement from what I did that he deserves credit. I hope he'll post it as a separate answer.
Output into a Tkinter window. Without scaling, the image is very small, but scaling adds about a dozen bytes to the count.

There's not much going on here except translation into Python and some basic golfing. Sometimes bit-wise manipulations are shorter, sometimes integer math. I could not find a way to pack more of the logic into lists or arrays. The basic algorithm is already pretty dense.
