The Queensland Art Gallery has a nice system of portable walls for its temporary exhibition galleries. If I recall, the walls are self-supporting and have internal wheels on jacks that raise and lower the walls--they roll into place and then a panel on the end opens up and the wall lets down to the floor, concealing the wheels. Their rooms are quite high, and I believe they must either use two walls joined at an angle, or tie them to the ceiling when used in a single plane. Of course, they take up a considerable amount of room when not in use, but I gather most of them generally are, so only a few have to be stashed. I believe the walls were designed by Senior Exhibitions Officer Joe Devilee and his staff. I don't have an e-mail address for the QAG, but perhaps Linda Young in Canberra can help there. Callers who can afford to ring Oz can reach Joe at 07.840.7319 (voice) or 07.844.8865 (fax). Joe has done a number of quite nice things with the designs of his Asian arts galleries and native plantings outside the Gallery, too. Don't miss it if you're in town. E-mail from: David A.
