Some interesting "Stream of consciousness" videos related to Math concepts:
"I like most creative activities that involve making a lot of noise, mess, or both. Aside from composing, I love improvising on various instruments, drawing, sculpting, and other methods of making things. My main hobby is mathematics, with special interests in symmetry, polyhedra, and surreal complexity. This usually manifests as collaborative research in computational geometry and other areas of theoretical computer science, or as mathematical art."
