Smash Putt brings 'mini golf apocalypse' to 12th Ave

Fore! Smash Putt, "a temporary mini golf course/art installation on Capitol Hill," is open for play:

Assembled inside a dingy 12th Avenue building by Rusty Oliver and a group of industrial artists who call themselves the Hazard Factory, it's 10 holes featuring crazy contraptions involving catapults, air compressors, power tools and 33-1/3 rpm turntables.

At hole No. 2, which is called "Driving Range," you can launch a ball through an air-powered machine gun toward the upturned innards of a piano: "Clang — ng-ng-ng."

At hole No. 5, "Roulette Francaise," a motorized scooter turns a platform that shoots your ball off in one of four directions — one containing a hole. (And feel free to toot the scooter's horn whenever, just for fun.)

There's also beer and snacks in the Miniature Golf Apocalypse clubhouse. You can buy tickets and get more info at http://www.smashputt.com/ The playing season is a short one -- Smash Putt will only be open for play these final three weekends of November.

The Hazard Factory is also responsible for Seattle Power Tool Races event. Here's a video of some of the, um, technology behind their putt-putt course:
