For just $300, you can have a part of your brain sliced away. And the first 30 customers "get to keep the ice pick" as a memento. Say goodbye to your problems!

One of the more interesting and controversial installation pieces at Nuit Blanche this year was by Toronto's Dan Bergeron (aka fauxreel). Well known to Toronto, Dan took his billboard hack style one step further this time. By including a live phone number and recording the messages left by his viewers, he was able to make his piece interactive.

If you're at work or have kids around, use headphones (coarse language alert):

It seems that a fair number of Torontonians are open to the idea of having their prefrontal cortex sliced and diced to restore their sanity. Others take offence to the notion.

The phone number is still live, and taking messages.

Thanks, Dan, for sharing your audience reaction with us.
