Hey, first time poster, check out
Smashputt, which is in portland for 3 more weekends. Its hard to describe, but this is from the website:
"Ball destruction, Centripetal Actuators, Accelerator Pads, Ball
Bouncers, Moving Walls, Roller-Skating Logs, and Secret passages. No
golf ball survives the assault of Smash Putt! A new course of
deviousness and dastardly delights from the hands of an all-star
assembly of artists sprung from asylums across America. Each and every
hole is dripping with excitement!"
A group of artists, hackers and DIY folks built the course, and I thought the Open Tech Space community might get a kick out of it.
