The good news is the images are quite interesting and respond very quickly to mouse and keyboard events:
The bad news is :
- A limited set of browsers support WebGL
- Those that do seem unstable
Using the latest versions of Chrome and Safari on OSX I have found that browser windows will occasionally burst into periods of rapid flashing that look like they could induce epileptic fits. Also the screen will occasionally lock up a machine with the dreaded spinning beach ball for long periods. This happened on both desktop and laptop machines.
For these reasons I have opted to stick with a Google Earth KML file for this sort of content until WebGL support improves.
