Bruun Idun is holding a twisted piece of driftwood and playing an Orca song. The whimsical troll sculpture, one of six installed in the PNW by Danish recycle artist Thomas Dambo last year, is tucked away under big trees near the Lincoln Park shoreline in West Seattle. The other trolls are in Vashon Island, Bainbridge Island, Issaquah, Ballard and Portland. I have already sketched the one in Ballard, so I now have four more to go. How many have you visited so far?
