Duct Work Panorama, originally uploaded by dagnyg.
Looks like some kind of weird insect, but it is the ductwork for our room addition called The Barn. The plywood platform, or the insect head, is where the furnace and a/c evaporator are installed.
This is a 4 image panorama, taken lying on my back on the floor. Nikon D80, Nikkor 12 – 24 wide angle zoom. Combined in Adobe Photoshop CS6
