Markup Review

A nice little web app that creates a spinning loading graphic using canvas, with a VML fallback for non-supporting browsers.

The diameter, FPS, speed, colour and other variables can be tweaked to customise the graphic.

In the markup there is a header for a div rather than for sectioning content, and there are opportunities to use input type="email" and input type="color", but overall a nice use of canvas and HTML5 in general.
