Chrome Experiments is designed to showcase how Google's browser can handle sophisticated Web applications.
Among the 19 examples so far available: beach balls bouncing from one browser window to another, control-tab animations, fractal trees, and 3D image modeling.
So it should be no surprise also that when visiting the site with a non-Chrome browser, you're presented with a warning: "We highly recommend you launch this experiment in Google Chrome. It may run slower, or not at all, in other browsers," then offers a handy Chrome download link.
Google has been advertising Chrome, too, which is unusual for the company. Clearly it has high hopes for the browser.
Of course, all the experiments worked for me in Chrome, but I tried them in several other browsers as well, with mixed results. One of my favorites, Ball Pool, which lets you spray patterned circles that stack up, then shake the window to make them slosh around, was illustrative. On Firefox 3.1 beta 3, it worked fine. On the Safari 4 beta, it worked, but sometimes with edges of balls sliced off. With Opera, the balls moved smoothly, but shaking the window didn't work. With the Internet Explorer 8 release candidate, it didn't work at all.
