That's pretty cool, there're three problems though:
First, the link is broken (403 forbidden, probably either a permission issue or lack of an index page), so I had to go up a directory to access anything, and the source is inaccessible.
Second, the user would have to confirm a security popup in order for the applet to run, since java's security policy disallows access to anything related to hardware accelerated rendering (even opengl), so any user visiting the page would get some unknown popup when they visited the page, probably assume it's malware, and leave.
Third, the security popup never came up, and the code didn't run. I'm guessing the code is probably throwing an exception somewhere and failing before it gets a chance to ask the user for permission.
I was doing some fiddling recently, should be fixed now.
Thanks for letting me know about the missing index issue, I recently migrated that site from apache to nginx and missed that.
As for the "unknown" applet problem, the idea is to ask users to voluntarily open a new tab with the applet running - my users trust me enough not to screw them with malware, and so I don't.
