Draw boid independently of size
Draw a bunch of boids in different sizes
WIP: start work animating the boids
WIP: animate boids based on potential fields

I'm building an ... arena I guess you could say ... that the boids will
"fly" around in: the middle of the arena is shaped like a pyramid with
rounded corners and the outside is like a moat with a round bottom. The
effect should be that the boids always stay in the moat. I'm also going
to "tip" the arena for each boid so that they all "float" around the
moat in the same direction.
Switch to array to keep numeric coords

Using an associative array would be men converting the region
co-ordinates (i.e. the co-ordinates that describe which region the boid
is in, and thus, what function to use to calculate the "potential
field") to strings, which is gross.
