This little VW bus is actually the world's smallest vinyl playback system. Here's what happens: the bus travels in circles around the vinyl on its cute little wheels and a "stylus" on the underside sends the signal to a battery-powered sound system and a speaker on the top.

Go check out the video demonstration of this thing. It's actually a lot more amusing than you'd imagine. I've seen these for sale before, but the link appears to be purely for demonstration purposes. You can go here and purchase one for $100. They call it the "vinyl killer" and comes in pink so, yeah, be afraid. Be very afraid.
