Picozu is an online image editor that uses the
canvas element and other HTML5 technologies. Appcache is used to store images used in the app’s skin for offline use, and
localStorage is used as part of the Facebook integration.
In the markup the
menu element would be a good choice for the list of commands used, possibly with
toolbar set as the
type. There are also a couple of
type attributes in the
script tags, but other than that a very smart piece of web development.
