Guess what we're building!

A prize will go to the person who can guess what we're building with these objects in this picture:

In case you can't tell, that's 16 right angle PVC pipe connectors, 3 10-ft long 1/2 inch PVC pipe, 1 2-ft long 1/2 PVC pipe, cable-ties, poster-board, and tools.

The answer will be posted Sunday afternoon/evening, March 13, 2010 (because that's when I'm expecting to have some available time to blog). Good luck!
