And a fantastic compliment for the Colors developer, it must be awesome to know your hard work is appreciated by so many people, and is reaching out to audiences that even Nintendo didn't dream of appealing to.
Sounds interesting but it's really hard to find information about it. I'm not surprised we've never heard of it before, it seems to have been an exhibit at a software show last March and nothing's been said about it since. Google doesn't turn up much info and the official site doesn't say anything about the program itself or it's features but there's a demo video of it running on youtube. Looks like it's got opacity controls but I can't tell if it's pressure sensitive. The animation side of it looks amazing. Pretty cool if they manage to get it released.
