Notably one of the first people who whipped out a credit card to buy the 3D CAD/modeling program Rhinoceros 3D at v1.0 on the first day it was available for purchase:

which engendered the opensource node editor Grasshopper eventually expanding to a ménagerie of animal-named support applications.

Rhino 3d was the first 3d modeling app I had ever used. I was in high school. It was so hard :-) but very cool.

Used to take an hour to render a simple teapot. I could probably render that in realtime now.
