This week, one artist makes crystals from scratch, another paints portraits of people who share his name, and a third focuses on the rhythms of the StairMaster.
"Show and Tell" at the Armory Center for the Arts is a group exhibition that continues through September and consists of events rather than a collection of artworks. This week, artist Emilie Halpern will demonstrate how to grow various kinds of crystals, using ingredients you probably already have around the house. Artist Alice Könitz will help visitors build models of the landmarks they most rely upon when navigating the cities where they live (whether Los Angeles or elsewhere). 145 N. Raymond Ave., Pasadena; Fri., July 27 & Sat., July 28, 12:45-5 p.m. (626) 792-5101, armoryarts.org.
