Isaac made an awesome update animation, available here:

Despite a few obvious issues, it provides a great perspective on the shape as 
it currently stands.  That heart primitive is described by a polynomial 
equation that has been useful in seeing how well our root solver is at handling 
complex sextic(!) roots.  Quite a number of challenges ahead, but awesome 
animation.

Anyone else have some cool progress to share?

Cheers!
Sean
