Flickr user Christopher Holland created this excellent little sculpture. I commented on the photo on the originating page:
"This is really cool! It appeals to both my nerdy-technical and creative/design-oriented sides.
I like the continuation of the air stream concept in the lines on the box top as well."
Anyway, I dig it :-)
