1. Mathematics Seminar Random Dot Stereograms: The Geometry behind the “Magic Eye” pictures If you’ve wanted to learn more about the “Magic Eye” posters and images, then come to this thirty minute display of stereograms, the geometry behind them, and some programs that create them. (Note: I can’t guarantee that you will leave always being able to see these images…but at least you will better understand them.) 1:00 p.m. Thursday, February 8 104 Centennial Hall
