Considering Ristar only had the one game on the Mega Drive, there sure is a lot of nice fan art of the character floating around on DeviantArt (a majority of them are coming from one artist, mind you). The game itself was one of the true gems from Sega's 16-bit days, and one of the best platformers from that era.
