Renwick Gallery -- a newly renovated Smithsonian art gallery across the street from the White House -- has opened its beautifully restored rooms to a WONDER of an exhibit.

WONDER honors this historic building, the first in the country to be built exclusively as an art museum, with room-filling pieces created specifically for the Renwick by nine contemporary artists.

The gigantic art -- a rainbow made of thread, a pieced-together cast of a 150-year-old tree, a gorgeous wallpaper made of bugs and Bryce Canyon-like hoodoos made of paper, tape and toothpicks -- invite the viewer to peer closer, to see the tiny bits and figure out how it works. Some of the work asks you to interact with it; others -- like the rainbow and the bug wallpaper -- require the poor security guards to work overtime to keep the crowds back from it. It's a wonderful exhibit for children and my husband -- you know, the people who aren't huge fans of art museums. And, because we're spoiled rotten here in D.C., it's also free!

I could keep typing, but why. Click on the pictures to take your own virtual tour of the Renwick Gallery, then come soon to see the real thing. The second floor, with its amazing bug wallpaper and deconstructed tree, will close May 8. The first floor closes July 10.
