<p>[QUOTE=&quot;messydesk, post: 4797202, member: 1765&quot;]Could be 10 years that I first put one of these together.&nbsp; I get requests for them now and then, but not often.&nbsp; The coins have to really warrant it.&nbsp; I discussed this &quot;new&quot; technology on a thread on the CU forum yesterday.&nbsp; The novelty here is in the ability to control the animation with a phone containing a gyroscope and accelerometer to simulate tilting.&nbsp; At its core, it&#039;s still just an animated GIF.&nbsp; 24 frames at 300x300 if you download it.&nbsp; On the server side, they are stored at higher resolution.&nbsp; The client-side application seems to interpolate between frames, as it is very smooth for the frames being 15° apart.&nbsp; 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&#039;s what I&#039;d build).&nbsp; It&#039;s a very useful way to present a coin image, and complements the standard, high quality static image.</p><p><br /></p><p>As for the drawbacks of GIF, they aren&#039;t too serious with coins that don&#039;t have much color, because the color palette limitation isn&#039;t an issue.&nbsp; Lustrous toners present a bigger problem with color quantization.&nbsp; A better format is APNG, which has no color loss, but it&#039;s not standard enough to use for whatever reasons.[/QUOTE]</p><p><br /></p>
