Snowstorm, work in progress #2: Hardware-accelerated CSS 2D/3D transforms / stress-testing
Here's Safari running just over 250 individual snowflakes (rendered as a @font-face "webfont"), including opacity, text-shadow and 2D + 3D rotation transform effects. CPU peak was perhaps 75% on an early 2008 Mac Mini.
It's worth noting that Chrome really chokes on the same full set of glyphs with many points etc., but performs better with a reduced/simplified set.
Also, happy holidays! :)
