I remember waiting 30 minutes for a crappy vrml model of the Enterprise to download over a 28k modem years ago. This is both impressive, and makes me feel very old.
It locks up my browser and takes 20 seconds to render one frame. (I guess that would be 0.05 FPS.) So: no, not really impressive. Feels like a regression, actually. (At least the mobile devices of 2015 managed to do 3D acceleration properly. Too bad that desktop never caught up and that the mobile landscape formed by accident due to commoditization, not due to an understanding of open standards.)
