`SQUINT,' Jack the Pelican, 487 Driggs Avenue, Williamsburg, Brooklyn, (718) 782-0183, through Oct. 17. This aptly titled group show challenges the eye with effects both miniscule and manic. In the latter category is Devorah Sperber's actual-size replica of Jackson Pollock's "Autumn Rhythm," accomplished with 165,000 pipe cleaners. As for tiny, there is Mark Shetabi's peephole version of Mary Boone's SoHo gallery and Lars Kremer's composite dragonfly made of images of a tiny dancer. The thrills are mostly cheap, but they're still thrills. -Roberta Smith, October 8, 2004
