Here's a good example. Click on "live demo" in a WebGL browser - should be most recent browsers. It might be fun to have the new release page replace a model image with a WebGL preview if WebGL is detected, or just have it on a separate link. There are even
model viewers in Javascript now but they are slower.
The nice thing about WebGL is that ...
1. No plugin installs needed ("just works").
2. Is part of web page context so for example right click -> view image gives a normal image of the current model view.
3. Is all open source, non-proprietary ... no flash or obscure plugins !
So it might be another way to create interest and/or salivate over new models of vehicles or weapons.
