It's really not that impressive. The zoom doesn't go down very far - you'd be better off just loading up a Mandelbrot program and viewing it yourself. If you're on a reasonably decent machine (mine hails from December 2007), you can zoom much further than this before running into long calculation times.

Ugh silverlight...
Couldn't view this on my iPad
I don't understand your downvotes. That's correct, the iPad offers a nice window into the internets, but it's a small window that only lets you see certain things. Large swaths of the internet are inaccessible to the iPads of the world. No longer to site authors have to check user-agents to restrict Apple users from seeing the site, all they have to do is put in a bit of flash.
