Awesome, especially in black I think. But WebGL still has an aliasing problem, made worse when we introduce movement. It was the same in the watch movement sim on HN a few days ago. Not to take away from the amazing work of the authors, but are there higher quality anti-aliasing options which won't cause my eye to distract to the high-velocity pixel movements on the car's shutlines as it moves along? (Full HD machine - dunno if this issue disappears at HiDPI).
Oh and another thing. PlayCanvas looks great but also looks properly expensive. I'm having to cough some pretty serious dough as a single experimental developer, without even getting above bronze support. Not hugely garage-outfit friendly though I will say it looks very professional.
