I scored the damndest crapgadget yesterday: Disney's Disneyvision is a little box styled like a vintage TV. Where the tube would go is a flexible plastic wand attached to a variable motor, lit by a strobing white LED. You put a wiggly rubber 2" characters on the wand (effectively sticking the wand up its butt), turn on the motor and the light, and the strobe creates a zoetrope effect that makes it seem like the characters are energetically dancing.
But the damned thing is the variability — the resonant frequencies of the characters' appendages kick in at different motor-intensities and the strobe-frequency produces even more surprising choices. There's a sweet spot where the characters appear to be in a kind of holo-tank, dancing or fluttering, but there's also a whole range of totally glitched-out possibilities in which the character flicker through what appears to be a kind of hilariously horrible video malfunctions.
There's not much about this toy online, and I think the main reason is that it's practically impossible to video-record. Getting phase-lock between the strobe and the camera requires a lot more video-kit than I have to hand, and otherwise, the video comes out pretty disappointingly (see this review for a valiant try, and here are a couple I made).
The toy is sold in Disneyland (and possibly other Disney parks) for $30. It's worth a look just for the sheer imaginative, improbable weirdness of it. I'm going to use mine for a night-light.
