I saw this cluttered work by Alberta artist Chris Millar at the "It Is What It Is" exhibition at the National Gallery in Ottawa a few months ago. The exhibition featured a lot of interesting contemporary Canadian art, but this is the one that stuck with me. At the time, I had to compete with a large group of middle-aged women to get a good look at this thing, but from what I can tell it's a factory of sorts which produces brightly coloured skulls. Andrea Williamson of Shotgun Review has a detailed review that attempts to explain what's going on here.
You can see more of Millar's work here.
