Waltz of the Roses animation (3D WebGL model). Surprisingly 7 rendering calls (for 7 roses) are smooth on Nexus 10. We need an artist to make them really dancing. I'm not a good one (Lissajous figures are used :)
Tchaikovsky's "Waltz of the Flowers" WebM 5Mb file from globalmusicdownload.com is used. "Art requires sacrifice" (roses itself takes only ~20Kb). You need WebM codec for InternetExplorer (and Safary?).
Simple animated rose. More examples.
