For those of you who found the visual-arts offerings at Bumbershoot fine as far as they went but a little thin on the ground, the "NEPO 5k Don't Run" may satisfy your appetite for aesthetic overload.

It is, frankly, a monster.

Five kilometers long! Eighty artists, of different stripes, involved! Interactive artwork! Live music! Refreshments! Light rail!

Light rail?

Yes — the idea is this: You meander at your leisure (no jogging, sprinting or pole-vaulting allowed) from Pioneer Square's Occidental Park, through the Chinatown International District, eventually winding up at NEPO House at 1723 S. Lander St. That's a couple of convenient blocks away from Beacon Hill light-rail station, allowing you to return to your starting point in an efficient manner.

En route you'll encounter a "bar code poem," a wheat-paste mural, a tree-map, a fold-up elephant, a "windy intervention," some "Liberated Stationary Bicycles" and dozens of other oddities. Featured artists include Mandy Greer, Mike Pham, Claire Cowie and Troy Gua.

The walk starts at 2 p.m. Saturday and concludes with an art exhibit and various kinds of entertainment at NEPO House or nearby, starting at 6 p.m. and continuing into the night.

What, exactly, is NEPO House?

In the words of its founder-curator, Czech-born Klara Glosova, it is a private home that has become "an experiment in integration of art into domestic environment" and "a homing device for experimental, multimedia projects."

Glosova has reached out to other galleries between Pioneer Square and her home, to make the "NEPO 5k Don't Run" into a marathon art walk festooned with a superabundance of zany bells and whistles. For maps and more information, go to www.nepohouse.org/nepo5.html.
