from the creator:
“We made Disctop to bring a bit of fun in working with your brand new iMac G5, although it can be of use as well, and not only for owners of an iMac. Normally when you insert a CD in your Mac it disappears, but where does it go? They simply pop up on your desktop! After installing Disctop, your inserted CD or DVD slides in from the side and neatly fades back into your desktop picture. Now you always know if there’s a disc inside, and what type it is. Of course there are plenty of things to tweak and make Disctop fit your Mac perfectly.”
Here’s the images from the pref.pane.
Beatiful, great, but unuseful? Try it. The CD inserted cover a big part of screen (with a 17″ inch imac) and you have to light it all!
