I hate the cold, so I currently have a hat on, my hood on, two blankets, slippers, two pairs of socks (one wool), my pants tucked into my socks, etc. I look really strange, but w/e.
I had the idea to turn my desktop so that the exhaust points at my feet, since warm air comes out of those holes. I opened blender and have a couple high-poly cubes in it, and when I want to up the heat it's producing, I'll switch to that and rotate it around for minute (there's enough faces that it lags really badly when I do that).
I wish someone would print a bunch of stuff; there's a big printer directly behind where I sit, and when it prints, it blows warm air on me. :P
What creative ideas do you have to stay warm?
