Check out hep-outreach.uchicago.edu/. The past few years, together we my colleague David Miller, we have run the Fermi Summer Interns Program in Science each July on the campus at the University of Chicago. A short video produced by Fermilab explaining the phenomenon of neutrino oscillations where I get to play the tuning forks - I think that's one step below the cow bell, but one above the triangle. I participated in the Quantum Diaries project run by the particle physics news site Interactions.org in 2009. Here's a link to my blog. The streaming video of my Physics for Everyone lecture on neutrino physics at Fermilab in 2011.
