Sorry, but it isn't as nice as I expected. It's essentially an underlay of the default Mac OS X desktop. The same that I use on my G4. Having just the G5 layout would be nice.
I used to have a photo of my boss on transparent way with the aqua desktop as if he was looking angry at me ... that was funny until he saw it ... Now, I prefer to rotate the desktop picture every week...
Nice idea, not very well executed, and a bit messy... I'll go with those who voted this 'average'...
And kind of silly to use on (or modify for) my iBook... ...unless you hooked it up to an iSigth and really got a semi transparent image of what's behind the screen, that would be kind of ...
