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.
I'll add more tomorrow and now it's time to hit the hay!
