@wezu: It’s real! I’m afraid I don’t have Roaming Ralph ported (yet). I will have to compile the CPython interpreter to JavaScript for that. (There’s a sentence I never thought I’d say!)
If this is more convincing, here is the animated Panda model in pview:
rdb.name/panda3d-webgl/pview-panda.html
Drag middle mouse to rotate. Also try W, to toggle between wireframe modes, or Alt+Enter to switch to full screen mode.
@stereoscopic: oh, you’re right! I didn’t even consider that. It appears to run on my Android phone as well, although touch events are not yet supported.
