If you're going to make a PC, at least have it DO SOMETHING.
Like my old company's main computer, the iBlock v5. Not only could it take your picture, work as a webcam for other iBlocks and MicroBlock PCs, you could also make lovey music with it.
Just add a bit more features, instead of just having SetRandomColour and a whole bunch of buttons.
EDIT: Also, if you actually to add more to it, I'd be willing to send you a copy of Fireblox 5.6 (A Blockintosh side-company) for you to use in the build.
