I still can't nail down what I've done wrong. I know its just a matter of 
looping properly, but I can't get it right.

In other news, I've made an icicle out of blobbing 1/2 of a quartic, and it 
looks rather nice, so I may try that too.

But please, if anyone knows why this is doing what it is, tell me. I'm sooo 
close, but stuck.
