Acting as though they have successfully located the islands of Jonathan Swift's Lilliput and Blefuscu and have plundered them to their heart's content, the owners of Richmond's Artspace and Art6 have again amassed quite a collection of things tiny. Featuring miniscule works that measure no more than three inches in any direction by more than 400 artists, the collaborating venues present their biennial “Think Small,” a display of mixed media that includes shrunken sculptures, paintings and photographs. On display at both galleries through Dec. 20. Free. 232-6464 and 343-1406.
