Weekend Calendar: A progressive art show at Zip 37, a bon voyage party at Tamarac Square, everything guitar on the planet and more!

I wouldn't make much of its being Friday the 13th if I were you, because it's summer and life is going to keep on going, superstitions notwithstanding. Besides, what's so spooky about the following suggestions? Go, do, see.

Denver assemblage artist Brian Cavanaugh kicks off his three-sided adventure in collabarative art, Engulf, with Model Behavior, the first of three morphing exhibits on a theme that he'll install over the next few months at a trio of local galleries. Inspired by the modern dilemma we all face over how to balance material consumption and sustainable thinking, Cavanaugh's intent is to present works that change over the course of each show; an invitational element involves pie chart-shaped wedges distributed to 25 or more local and national artists that will be added to the overall installation incrementally, as Cavanaugh receives them. Slice will follow at Ice Cube Gallery in September, and after that, Flotsam and Jetsam will culminate the project next January at Pirate. But for now, see the skeletal beginning of Engulf tonight at a reception from 6 to 10 p.m. at Zip 37, 3644 Navajo Street. See the show through August 29; call 303-477-4525.

Guitar freaks everywhere - and their families - will converge on Copper Mountain for Guitar Town, a long mountain weekend tailored just for them. It all gets started tonight with a free live performance by School of Rock students, a Guitar Hero tournament and more; things really rev up tomorrow when a series of workshops commences, as well as an ongoing roster of free high-profile music performances on the Guitar Town Main Stage all afternoon (Richard Thompson is the headliner). It's repeat, only with different workshops and performers, on Sunday; family fun and the concurrent Mountain Home and Outdoor Expo are also ongoing.

In recent years, the nonprofit TACtile Textile Arts Center has taken over the role of anchor in the deserted Tamarac Square, where retailers have mostly jumped ship and few businesses remain. But all good things must come to an end (and, TACtile director Dianne Denholm intimates, rise again): The retail mall is now scheduled for eventual demolition, and TACtile, which supports local fiber-arts organizations and runs a gallery, needs to move and find new digs. Saturday from 1 to 4 p.m., Denholm will host an open house party; the last gallery show in the space, Controlled Explosions: Small Contemporary Quilts and Objects, will provide a colorful backdrop to the celebration. TACtile is at 7777 E. Hampden Avenue #114; call 720-524-8886.

Discouraged by the weak economy, some folks have grown ambivalent about touring those over-the-top luxury homes that the Denver Parade of Homes has always been famous for, and that translated into declining attendance for the Parade of the past. So, this year the Parade is introducing a new format: Visitors can tour 58 new homes scattered throughout the metro area and the Front Range. Although there are still eight Dream Homes included in the eclectic mix, the rest of the domiciles on view range from simple townhomes to mid-range family homes. And for the most part, admission is free, although Parade organizers do request a one-time $5 donation for the Muscular Dystrophy Association to gain entry to the Dream Homes. Visit homes from 11a.m. to 6 p.m. daily, through Labor Day.
