Bit of a tangent

For the past three months, I've been cobbling together a couple of graphics libraries and SDKs to allow me to make computer simulations that mimic natural processes.  I've gotten to the point I can make pretty neat raindrops. They wrap around the splash 'plate', so multiple copies of a master tile would lay together to make a larger pattern.  I can write the output of the simulation to a file that can be fed to a 3D printer. I hope to be making something physical out of this next year..
