The Boulder Museum of Contemporary Art is having a free day on Monday, and not only will it be blessedly quiet, but there will also be some cool stuff to look at.
Currently on display are the works of Henrique Oliveira, who does massive painted-wood installations that he calls "tridimensionals" -- basically, he paints on old, warped or discarded pieces of fencing or scrap-wood, and then arranges those pieces into something between a sculpture and a painting. Seriously, it's really cool to look at.
In a similar vein, Jessica Moon Bernstein uses inner-tubes and other commercial plastics to create installations using totally recycled materials that kind of resemble groupings of some weird life-form out of Star Wars. Either way, both shows appropriate cast-away materials, and both have the potential to blow your little mind.
All you have to do to see it on Monday is show up; the museum is open from 11 a.m. to 5 p.m.
