Adhesive 44: Fulfilling art writer John Berger's prediction that museums of the future would ultimately disappear and be replaced by personal arrangements of reproductions and printed ephemera, Brazilian artist Jac Leirner unpacks her decalcomania at the Miami Art Museum. Composed of hundreds of stickers adhered to two rows of window panes, and extending some 40 feet in length, Adhesive 44 exposes a universe of archetypal images that flicker in the mind's eye like constellations. This work speaks to the obsession with brands and logos by which humans organize themselves into groups and tribes. -- Michelle Weinberg Through October 10.

Existential Gravitation: Carlos Estévez's art is geometric and almost metaphysical. His craft is clean but not plain. "Existential Gravitation" retains a baroque whim in these monochromatic oils in which Estévez's preferred forms (circle and triangle) never really stir these puppetlike figures; they seem detached. A nave world of beings, flat, predetermined, driven by pure well-thought-out design. If they lived, they would lack complex emotions; they'd exist as essences rather than accidents. No mistakes, no regrets -- a neat world of body parts functioning in an orderly but hollow manner. It's here that an artist's intention matters as a sign there's more to this than a well-executed formal plan. -- Alfredo Triff Through October 9. Diana Lowenstein Fine Arts, 3080 SW 38th Court, Coral Gables. 305-774-5969.
I Can't Believe They're Real: Jay Oré brings back issues of planetary solitude mixed with plain stellar humor. Among conspiratorialists UFOs and aliens have been man's best-kept secret since the atomic bomb and -- during the mid-Twentieth Century -- our enemies, though not as menacing as modern-day terrorists. You're in for a treat here. Oré's photo collage is so labor-intensive as to put him in the same league with artist Tom Friedman. Oré is a prestidigitator of images, and a patient collagist, turning all sorts of menial lights into veritable UFO spacescapes, with which humans seem to interact quizzically at best. --Alfredo TriffThrough October 9.

Reconstituted Landscape: Isaac Asimov once implied that the microcosm and the macrocosm are one and the same. This becomes apparent in Matthew Picton's "Reconstituted Landscape," now on display at Damien B. Contemporary Art Center. Picton's installation of cell-like lattices in red, purple, gray, and orange, take over the gallery space. They hang from dozens of Slinkies on a frame and rise from the gallery floor through the walls. The well-realized environment evokes a gigantic synapse transmission, as if inside a huge brain, reminiscent of Richard Fleischer's aesthetic vision in Fantastic Voyage. -- Alfredo Triff Through October 20. Damien B. Contemporary Art Center, 282 NW 36th St., Miami. 305-573-4949.
