Unintended Consequences - Camera Obscura

This Saturday I was perusing the site of an installation (pre-installation of course) with Adam Rosekelly of f i e l d s. We were exploring some smaller commercial bays of a building currently under renovation when we stumbled upon the following in the last bay. The image was created by a suspended plastic sheet about 15' from the boarded up storefront.

(the lower image was created by adjusting the f-stop on the camera, it was much darker inside than shown)
It took a while to figure out what we were looking at but when we realized that the movement at the top of the plastic sheet was passing cars it dawned on us that a small knothole in the sheathing was creating the effect of a camera obscura. For clarity I have rotated the image (see below).

...and adjusted the f-stop a touch more (after stacking some things to hold the camera steady) which allows one to really pick out the shapes and colors. I obviously couldn't catch any of the cars on "film" since the exposure was set so long. However you could see the projection of the cars on the walls before and after they "drove" across the plastic.
We spent quite a bit of time watching the effect. I don't know if this is interesting to anyone else but the awe of discovering something like this was really exciting to me.
