DLRC Announces nuTilt

Could be 10 years that I first put one of these together. I get requests for them now and then, but not often. The coins have to really warrant it. I discussed this "new" technology on a thread on the CU forum yesterday. The novelty here is in the ability to control the animation with a phone containing a gyroscope and accelerometer to simulate tilting. At its core, it's still just an animated GIF. 24 frames at 300x300 if you download it. On the server side, they are stored at higher resolution. The client-side application seems to interpolate between frames, as it is very smooth for the frames being 15° apart. The lighting rig either rotates or is a ring of 24 bulbs that are controlled together with the camera to take all the pictures (that's what I'd build). It's a very useful way to present a coin image, and complements the standard, high quality static image.

As for the drawbacks of GIF, they aren't too serious with coins that don't have much color, because the color palette limitation isn't an issue. Lustrous toners present a bigger problem with color quantization. A better format is APNG, which has no color loss, but it's not standard enough to use for whatever reasons.
