Hi everyone, this is one of my first contributions to the site. I made up this battery theme today - As your battery charges the Mac in the picture gets more modern - Empty battery is an Apple 1, charges to an Apple II, to a Mac 128k, etc right up to powerbooks, G4 iMac, G5 iMac, Intel etc. The fully charged indicator is a new intel iMac. Also displayed on the monitor of each mac is a battery status icon showing charge status. To install you just use the standard method to replace the images in springboard.app, just the same way you change a carrier logo Hope somebody likes it!
