Does anybody remember the original Kalediscope for Macs. It was awesome for a different look other than Mac OS defaults. I suppose it went away with the classic OS.
I vividly remember the Scherzo theme; who could erase that memory? ;)
We emailed Greg and Arlo (authors of the classic Kaleidoscope) to see if they were cool with us repurposing the name and they were, you'll find their names in our app's About window.
here's the link
The web site of that program is kaleidoscope.net...it doesn't seem to have a Mac OS X version.
Unsanity created ShapeShifter, which is similar and worked on Mac OS X for awhile, but since Snow Leopard it seems Apple has changed enough of the system that it can't work anymore.
