Like Carousel USA, Turntable Works is another California-based manufacturer of large-scale turntables. But the latter firm has got a product I could not have envisioned: A portable, folding motorized turntable called the Pack-Man, which comes in diameters ranging from eight to fourteen feet.

Here's a sign you've seen too many building projects go wrong: At the six-second mark of the demo video, when the whole mechanism starts to tilt, I instinctively jerked my hands out towards the screen as if I could help the guy by grabbing it. But apparently it's designed or allowed, however inelegantly, to do that.

Didn't think it would fit a full-size car, did you? I like how they jump-cut the footage during loading, as I'm sure there was some finagling required to avoid driving off of the platform. But in any case the Pack-Man is an impressive feat of design and engineering, allowing one person to set the thing up in just five minutes.
