A whole lotta corporate angst is channeled into this riotous installation by St. Louis- and New York City-based artist Cindy Tower. Consisting of a massive, immersive piling of cardboard boxes, chunks of foam core and a profusion of bold-text signs, the piece is effectively a massive three-dimensional flow chart of how, well, the rich get richer through various loopholes in the U.S. tax code. Black garbage bags stapled to a far wall with giant dollar signs sprout rainbow arms that feed into a vast network of stockpiled forms: a menacing row of stacked and black-painted boxes labeled "Fabergé Egg Collection," "Speculative Collection," "Monsanto," "Boeing," "Copper" and the ilk; tiny cardboard house-forms labeled "Bring up the town with non-profit status" and "artist residency"; and to the far side, an oasis of broken-umbrella palm trees labeled "Cayman Islands." Everything is a means to preserving wealth, apparently, in Tower's eviscerating view of the democracy machine. The sheer immersive intensity of the exhibit says perhaps more than the copious text itself — a true monument to socioeconomic frustration and its many exploitations, at any moment this Nest Egg seems ready to topple and consume one and all — a case, of course, in point. Through March 30 at Good Citizen Gallery, 2247 Gravois Avenue; 314-348-4587 or www.goodcitizenstl.com. Hours: noon-5 p.m. Fri.-Sat. and by appointment.
