Nice project!

That is indeed a mysterious bug. Holding down the exclamation button  
indeed draws everything fine - even when setting generations to 1 or 2  
before startRegenerating.

And when setting generations to 1 another bug manifests: when setting  
to tick, the ellipse jumps to the lower left at some point.

I have no idea what's going on, or even how to debug this - will have  
to wait to next week (we're writing a paper ...).
