Flexicord
A simple invention here, but one with some merit - Flexicord cables can be gently bent into shape, and they'll stay the way you set them, the idea being that you can coil them up so they're always the perfect length, and never in the way of anything else. They're available in HDMI, Cat5e, RCA phono jack, S-Video and USB varieties in lengths up to 10 feet.
