What the eff is this?

Its the Easy Chamfer: http://easychamfer.com/index.htm

if you want it to be hard to guess, you should change the name of the picture before you post it. (roll mouse over the picture and it tells you it is a easy chamfer)

heh. That's pretty funny. Likely a result of posting at 5am. We do like how you wrote a comment at 8am saying it was the easy chamfer and then returned an hour and a half later to pimp slap us with the image name. Good stuff.
