Peace Wave Generator
I've never seen this guy before in Harvard Square, though he does sort of blend right into the mix of strange characters. His colorful Peace Wave Generator was making some music but not attracting much of a crowd when I passed by the corner of Brattle and Palmer. I checked out the web site on the bottom of his cart, www.professorworldband.com, and it turns out he's from New York and his been traveling the world for 20 years doing whatever it is that he does. The gizmo "uses the energy of music to broadcast peace waves throughout the world and works by making people smile and laugh," according to his website.
