If you work at the computer you might find it useful. Workola is an HTML5 application that works best with chrome and safari.
One of my favorite features is the 'tools section' and the resulting toolbar that appears once you add a tool. Similar to an igoogle page you can add tools/widgets to personalize your desktop. It's a hands on experience, free and requires no account.
click the + icon next to the 'my files' | 'upload files' buttons to see a few more sample tools.
Hopefully this helps a little,
