Montreal-based artist Michel de Broin created a hot tub out of an old commercial dumpster for his work Blue Monochrom. Found via the Make magazine blog. The artist’s site is here, and he’s also the creator of a number of other interesting works, including one called the Shared Propulsion Car, which consists of a 1986 Buick Regal sedan that has had its engine removed and been transformed into a pedal car for four people. Pedaling it around the streets of Toronto has gotten the artist into a little bit of trouble on occasion. There’s YouTube video of the car in action.
