But before you Google Search "Google Wave" and "Google Squared," make sure to check out this fun page, for Google Chrome only.
It does work mostly in FireFox 3.5b4. But because Chrome has such a powerful Javascript engine, its really the only browser than can run this page. Move the mouse, watch the page fall, and make sure to use the search box to do a Google Search. The results drop down from the top of the page. Use your mouse to sling the objects willy-nilly.
