Amnesty Hypercube is a new, free desktop widget platform for web widgets, flash games and video, including Google Gadgets, You Tube, Widgetbox and Yourminis.
With Amnesty Hypercube, you collect, manage, share and publish "web widgets" – snippets of code meant for your blog, home page or MySpace profiles. These can be placed directly on your desktop, or in offscreen "cubes" similar to Yahoo Widget Engine's heads up display.
If you're a Vista user, any widget in Amnesty Hypercube can be pushed into the Windows Sidebar with one click, which makes it a great way to extend Vista's library to every widget available on the web.
Amnesty Hypercube is in a public alpha release:
