On: Walk through a 3D model of Y Combinator

Such grid would mean that you can move straight only in 8 directions, all other camera rotations would need to be rounded to these 8 directions. I think this can result in quite 'jumpy' movement, but maybe human won't be able to notice such jumps?

I would definitely notice a jump like that in a video game, I'm guessing you'd need over 100 to make it seem smooth.
