I've successfully built a Retropie old school emulated gaming system with my second Raspberry Pi, using a Playstation 2 controller with a PS2 to USB adapter. This is plugged into my 61 inch DLP HDTV. (no pics yet, sorry)
Simple decorative project I did a year or so ago. Hollowed out book storage box, drilled a hole, and mounted clock to it. Simple, but looks SO cool in the living room.
