Thinking about approximating surfaces with little cylinders...
Got into pgh, realized I couldn't get the new room key
since housing was closed.
Tried sleeping at work, but noticed we didn't have a suitable
couch. I wound up sleeping the cslounge. Crosby showed up
and talked about crypto and worms until about 1:15. Slept
until 4:00, when cleaning people came in. Slept again from
4:30-8:15. Got into Morewood E210 after that, at last.
