// normals by angle, is there a large enough gap between normals?"
//
// If you think in terms of geometry, this means a collection of surfaces are all pushing on you.
// If they're pushing from all sides, you have nowhere to go, and you won't fall. There needs to be
// a gap, so that you're pushed out and have somewhere to fall. This is the same as finding a gap
// larger than 180 degrees between sorted normals.
//
// The problem is that on top of that, the avatar needs enough force to shove him out that gap (he
// has to overcome friction). I deal with that by making the threshold (360 - (180 - 60) = 240). I've
