Flustered

It's been another good week. We were introduced to GridWorld- some grid-based graphical educational thing. I made AI Pong with it. Then I worked on the raytracer some more.

I've done something to it. The problem is, I don't know what.

The four spheres are supposed to be reflective, but are doing some strange thing instead. They might be reflecting something, but not the way I meant it to, at least. And I've also checked over the math twice. I'll try and figure it out this next week; I probably just made some silly mistake. But you never know.
