Answer: Pixel Puzzle #132

The hidden picture is a pixel creature!

The finished pixel picture: a pixel creature.
Here’s what the colours make.

The picture as Python

Here is the same picture stored as numbers in a Python list. The program reads each number and prints a symbol for it, so you can see the picture appear in the Python shell.

picture = [
    "00000000",
    "00100100",
    "01200210",
    "00300300",
    "01100110",
    "01000010",
    "04111140",
    "00000000",
]
symbols = " #@*o"

for row in picture:
    line = ""
    for number in row:
        line = line + symbols[int(number)]
    print(line)

When you run it, it prints:

  #  #
 #@  @#
  *  *
 ##  ##
 #    #
