The little objects inside the arrows appeared to be white capsules (pills) and the work was one of my favorites at the Old Federal Building.
This is a set of encyclopedias that have been sculpted with cutouts and inlaid with imagery.
The photo doesn't do this justice - it's a futuristic cityscape made out of donated wire and tiles. You can click on these images to see them expanded and you might be able to get a better idea of details, etc.
This is one of a series of 3 large cut paper panels. The paper looks similar to the photo backdrop paper I use, but it's a larger size and the artists paints the backside which causes the color to reflect on the wall and shine through the filagree.
