When I was in art school many moons ago I had a life drawing class. We're all typically seated in a circle around the nekkid lady and at the end of a 30 minute drawing one of my classmates asked if he could borrow each of our drawings. Probably about 30 students in the class.
So a week later he came in with a VHS tape (90s!!!). He had photographed each of our drawings in order and made a short, looped animation of our model spinning 360 degrees. All of the different styles made it even cooler.
I'm not ashamed to say that my favorite model was a really built 20-something man with an intimidatingly big ____. I'm straight as an arrow but this dude was awesome. He knew I was more of a sketcher than painter so when he posed for my oil painting class he hung out during breaks and would do these crazy dynamic short poses. He was in shape so he could hold them longer than most.
The only "pretty" girl we had was a total beach and would complain about doing 20 minute poses, laying down. Nothing worse than focusing on a hand that won't stop moving. And she wasn't that hot, just hot compared to the usual Penn Station homeless people they paid in sandwiches.
