Suppose we decide to "improve" the geometry of something
	Let's make a cube with pointy sides
		That's not a cube anymore

If we finish early, and have more time:
	Since we can calculate normal vectors...
	If the normal vector points to the right post-MVP, brighten it up a bit
		This'll mean we have to calculate normals again post-mvp
		Dot product:  How closely two vectors align
	We'll talk more about lighting some other day	

Lab today:
	Add a uniform that controls how far the points stick out
	Set up a loop to animate longer and shorter cube sides
	Use the method from last week's demo to make a cloud of cubes, growing shorter and longer side spikes
