At first glance this pair of condominium towers rising over the Galleria Area appear to be unfinished. They may even look like victims of the latest hurricane or tornado to blow through the Bayou City. But what they lack in uniformity of appearance, they make up for in aesthetic pleasure derived from serious study. These are actually the first buildings designed by Cesar Pelli in Houston. They break the mold of surrounding towers by incorporating a crossword puzzle of color instead of yet another boring blue-green glass curtain. It's like sticking a pair of 40-story plastic flamingos on your lawn just to spite the neighbors. The red, pink, and cream-colored panels are all glass and if interpreted in the extreme, could be taken as a giant mosaic or stained glass window. In another departure from convention, the rooftops are red, complementing the panes below. Before this, even the most adventurous Galleria project only went as far as European green. In a neighborhood known for its uniformity in everything from stainless steel traffic lights to stainless steel arches marking crosswalks, this represents either a refreshing break from the ordinary, or a chaotic blight on the skyline.
