The International Museum of Art and Science in McAllen is hopping: first accreditation by the American Association of Museums, then a $25,000 grant from Wells Fargo for "Science on a Sphere," some kind of spherical projection screen developed by the National Oceanic and Atmospheric Administration to illustrate the earth’s environments, but adaptable for "any imaginable presentation suitable for projection onto a complete sphere." Now they’re having an art opening: Cande Aguilar’s exhibit World Affair opens on Thursday February 5, from 5:30 p.m. to 7:30 p.m.
