I have looked long and hard for CDU (Connectix Desktop Utilities). It is a very cool little control panel that lets you change the color scheme of System 7 among other things. It probably just swaps out a CLUT resource in the system, but I thought it was very very cool.

Does anyone have any idea whatsoever of where I could find this? I'm not sure even if this was a commercial or shareware product, etc. If anyone has any clues, please send them my way. It would provide quite the nostalgic experience to see this old control panel again.
