The problem with these for competitions where the source is submitted
is that render times can be scary. I have not insignificant cluster
resources but even that is limited. Personally I like the idea of
keeping these source based, it keep people honest and is a great
learning resource for users. I've had lots of positive comments already
from people looking at how things are done by experts in the fractal
contest.
