Artificiel is a group from Montreal I discovered recently (thanks Mouna!) who puts on some pretty awesome shows using objects like rubik's cubes and light bulbs.
I like how the focus is on the performance objects, versus on the humans manipulating the objects. This is how I think I'd be most comfortable performing, as I'm not much of a ham for the stage. Or for anything else, I don't think. Comfort aside, I'd love to be able to pull off such an elegant and engaging performance.
