The long-running Art Shanty Projects take over frozen Lake Harriet in Minneapolis beginning Saturday.

A total of 21 icehouses will offer art projects. Visitors can journey into the belly of a whale in artist Giuliana Pinto's Lonely Whale Shanty. Artists Anne Grinager and Sami Pfeffer take it lo-fi in the Phone Valet Shanty, where visitors are encouraged to leave their smartphones and pick up analog "apps," like hand-drawn maps.

More than 20 performing artists will brave the cold to do their thing on the lake, too: On Saturday, the Future's artist-in-residence Mr. Elvis leads "Homos in Herstory," a queer quiz; next weekend, visitors can spin on Willis Bowman and Karen Haselmann's Human-Sized Hamster Wheel.

It's all free, and you can download bus passes to get there at artshantyprojects.org.

(10 a.m.- 4 p.m. Sat.-Sun. through Feb. 11, Lake Harriet, Mpls. Access from parking lot on the lake's north side.)
