One time a visiting researcher came to our school for two days, and my then-current lesson was the one he chose to focus his writeup on. It sure made the hours I spent downloading KPS on the dozen MacBook Airs I had painstakingly procured for the 3D Club seem worth it. Another thing I really wish he had mentioned was that I had scored the software for free by waiting for a sale to promote the upcoming sequel. I guess what they say is true, timing is everything.
