Projects:
	Project 3:  AI and walls
		Make a simulation solving a maze
		Align with axis, to keep it simple
			So there are 4 possible moves:  +z, -z, +x, -x
		"Player" can spawn bots
			bot doesn't have to have a walk animation - can just float around if you want
			Should be evident which way the bot is pointing
			Animate turning and moving, not teleport
		If you want a nice, rather easy, AI that basically just does depth-first search
			Keep a set of explored nodes (stl::set)
			Keep a stack showing the current path back to the origin (stl::vector)
			A node is a position
			Until the goal is reached:
				If an unexplored option exist:
					move to it
					add it to the set
					add it to the path stack
				else 
					pop the stack

	Project 4:  Maybe something with rolling balls

	Final project:  A game that's arguably fun
		
Next game engine improvements:
	Time:   We started this one a while back
		I debugged the time code
		Will hand move a time number
		Another way on time:
			glfwGetTime
			Can set it too
	Spawning items:
		Maybe we need to be able to change "weapon"
		Mouse wheel is the usual way here
		Let's spawn blocks, and snap to the grid
	HUD:
		Let's make an aiming point today
		Words:  Create a texture, put it on a panel
