Recently I dyed 30 new Flipping Physics t-shirts. Get yours while you can!! There is also a time-lapse of the entire day of tie-dye and a sunset time-lapse just for good measure. (Both near the bottom of the page.)
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
