I am part of the program committee of this years Video/Multimedia track for the Symposium of Computational Geometry (SoCG). The call for videos/MM presentations went out just a few days ago. Preparing a video means a lot of work, but it is also a lot of fun. I did a video by myself with Kevin Buchin (who is chairing the video PC) back in 2007. See here for the video and see the related animated gif below.
