If you have an Apple TV and are interested in some of the exciting things you can do by hacking it (e.g. adding additional video codec support like divx, etc.) but have been too chicken to try it yourself, you may be interested in the aTV Flash from Apple Core. Basically the aTV Flash is a patchstick -- a USB flash drive preloaded with software to modify the Apple TV OS. You just plug it in to your Apple TV and it automatically hacks your Apple TV to add multiple codec support, SSH access, the Couch Surfer browser, and much more.
