Podcasts
In the fall of 2007 the students in my Math 301 (Great Theorems and Ideas in Mathematics) course created podcasts of great mathematicians and great ideas in mathematics. The series of podcasts, called The Shoulders of Giants, can be found on iTunes, on the Dickinson Blog, or on the air on WDCV.
