(There's no video for Chameleon 2.x yet. Please contribute to MR and add a video now!)
Chameleon 2 was a nice utility to change your desktop's pattern. With Chameleon 2 you could create, edit with an in place pixel grid editor and apply/install desktop patterns permanently, as well as browse and IMPORT "ppat" ressources from other apps in just a mouse click! It supports patterns from 8x8 all the way up to 128x128.
Chameleon is the commercial and beefed up version of the shareware software Before Dark from the same author.
