When I opened this for the first time I was really excited. It seemed like a really in-depth API/library with a lot of options. But when I started actually using a lot of their demos with Firefox 3.5 I noticed how many visual and coding compatibility issues there are. Things are quite often visually "odd", and sometimes values simply return NaN.
I couldn't get a single demo to show up in Safari 4.0.4.
Or Chrome, so perhaps Webkit is not supported yet.
The site completely puked in Opera
I just tried this on my iPhone and it turned into a Droid.
