I´m also surprised, how small your gif-file is. fl64: Could you please let me know how you created those single gif-layers? Did you draw every single layer in inkscape and export it as a png ?
It remind me that computer game called "alley cat" .The screen was an 8 colors (i think it was in the 80es !) and the computer was an olivetti. I had to type cat.exe on MS DOS to play. Lovely game.http://en.wikipedia.org/wiki/Alley_Cat_(video_game)
