A Century of Collage
The Elizabeth Leach Gallery turns 25 years old this month and celebrates with a terrific show of collages from artists like Bruce Conner, Robert Rauschenberg, Ray Johnson, Kiki Smith, and Jack Pierson. So it's their birthday, and we get the sweet gift? Doesn't seem fair. Elizabeth Leach Gallery, 417 NW 9th, 224-0521, through Dec 30

Dwarves Build a Castle
What's cooler than an Austrian slide show of Lego men building Lego castles? OK—a lot of things. But what about 3D Lego men building stereoscopic Lego castles? A little bit cooler, right? Right? 3D Center of Art & Photography, 1928 NW Lovejoy, through Dec 31, $4

Fourteen Artists/Fourteen Years
For the past 14 years, Mahaffey Fine Art has served as Portland's premier fine-art printmaking studio. This exhibit culls 65 prints from Mahaffey's history, including works from Hans Haacke, Robert Morris, Jene Highstein, and Tony Fitzpatrick. Portland Art Museum, 1219 SW Park, 226-2811, through Jan 14, $6-10

Peter HappelChristian
Tilt Gallery presents the work of Ohio artist Peter HappelChristian, who "systematically collects dust from a variety of spaces, both public and private." The dust is then used in photographs, sculptures, and handmade books in an artistic exploration of "human residue." Tilt, 625 NW Everett Suite 106, (908) 616-5477, through Sat Nov 25

Ty Ennis
Ty Ennis, he of the Oregon Biennial and annual NAAU solo show, returns with a new suite of drawings on the topics of sex, death, friendship, artmaking, and memory. Ennis creates some of the best works on paper in the city, so this should be one of the don't-miss shows of the month. New American Art Union, 922 SE Ankeny, 231-8294, through Dec 10

Vaughn Bell and Latonya Hicks
Disjecta's current show highlights the work of two quite different artists: Vaughn Bell suggests absurd methods for reconnecting with nature in projects like "Biosphere Built For Two" and "Garment for Flora-Fauna Relationship," which is a sort of smock with a built-in planter for a small tree to grow over the wearer's heart. Latonya Hicks from Florida has created a hair weave salon, rooted in contemporary African American customs and gathering spots. Disjecta, 230 E Burnside, through Dec 3

Green Light Green Light
small A's latest offering is a group show of three young New York artists whose work concerns itself with the absurd pathos of everyday life. Jamie Isenstein (formerly of Portland) has two new installations planned for the exhibit; Anissa Mack famously placed fresh-baked apple pies in front of the Brooklyn Public Library for passersby to steal; and Josh Shaddock works with language and humor to suggest tiny disruptions in the daily routine. small A projects, 1430 SE 3rd, 234-7993, through Dec 23

Pierre Huyghe
Although Pierre Huyghe's body of work is incredibly diverse, it nonetheless demonstrates the Paris-born artist's obsession with creating layered narratives—only to expose the entangled network of relationships that compose them. For Huyghe, whose video "This Is Not a Time for Dreaming" marks the Jubitz Center's fourth contemporary art exhibition since it opened last fall, there is pleasure to be taken in peeling back levels of signification. "Dreaming" originated when Huyghe was commissioned to create a work to celebrate the 40th anniversary of Harvard University's Carpenter Center for the Visual Arts, the only building designed by the architect Le Corbusier in the United States. The result was this 24-minute video in the form of a live puppet show, in which Le Corbusier's frustration in working with administrators to realize his vision is paralleled with Huyghe's own stifled attempts to complete his commemorative commission.
