This iPad dock built from the left over husk of an old iMac reminds me of that scene in Toy Story where the toys crawl out from under the bed with miss matched parts. The iMac base looks a bit tired, but on top of that base is some iPad lovin'.
This dock is certainly one of the better that I have seen. It would make that iPad very usable at your desk in the home or office thanks to the Bluetooth keyboard and comfortable iPad working height.
The builder of the device simply goes by Rusty and he doesn't really get into details about how he pulled the creation off. I want one though, that would make a nice nettop for surfing the web.
