Walt Michelson mailed with news of his 50 synesthesia-musicboxes. Each of these pays homage to a different musician.
His Beefheart musicbox, Ant Man Bee Massacre in Beeftroutwinter, is currently on show at Galerie Otto Schweins in Köln.
Which particular Beefheart music you hear when you look at it is, I suppose, entirely up to you. For further explanation see Dr Michelson’s email.
