Answer: Pixel Puzzle #55

The hidden picture is a pixel creature!

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 = [
    "000000",
    "001100",
    "023320",
    "040040",
    "033330",
    "000000",
]
symbols = " #@*o"

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

When you run it, it prints:

  ##
 @**@
 o  o
 ****
