I'd like to say thank you to Fran Jurga for publicizing a video that I created during my PhD.  She wrote about it on her HoofBlog website, and since that time it has received a lot of attention.
It's great to see that something I worked on during my PhD has been so immediately useful for people.  My PhD involved a lot of "basic science" work, which rarely has immediate influence.  It helps a lot with motivation to find that people are so enthusiastic about it.
