Instead of what I should be doing I have spent the last hour trying to get familiar with some of the bells and whistles of Lion. The fact that various functions are controlled by how many fingers you have on the trackpad is...interesting. I think I'll ultimately find it useful. Right now it is just...interesting.

In other news, by noon tomorrow all of my students' work must be in, at which time I will bury myself in the grading process. Today is just trying to draw a few deep breaths in preparation for the plunge.
