366 • 140 • Tetrahedric symmetries
I had an exam in algebra today, and there were two permitted aids; a calculator, and a tetrahedron. Looks like my professor have been bending pipe cleaners all night long, because we all got a cute little tetrahedron each, handed out at the exam. It was quite useful though, in describing the group of symmetries on the polygon.
The exam went quite well. (I was actually supposed to have this exam last spring, but I managed mess up the time and location, and got there too late.)
Lighting info:
SB-600 on the floor beneath me, pointing towards a home made aluminum foil reflector under the camera. Triggered with Nikon CLS.
