It took me 3 days to draw this "COLECO VISION" ambigram and to make it spin as a valid ColecoVision rom file. In this version I've played around based on a few questions/suggestions in AtariAge forum.

Some technical details. It uses Graphic Mode 1, 2 charsets (almost full) and 6 screens (frames), 3 screens per charset, and a data sequence to create this animation. The idea is to set during the NMI the proper screen with its proper charset for each frame and that's it. The rom file is pretty much uncompressed but still small (less than 6KB).

Download file... soon available with source code.
