I like to unroll things with the Abelson Scopeworks Omniscope pinhole camera.
This is the wheel from a firetruck. The camera was aligned with the center axis of the wheel. The Omniscope 'sees' a donut shape, just shy of a 360ยบ circle. The image captured by the film is an unrolled version of the donut - in effect, a polar to rectangular conversion. For this image, I used Kodak E100GX, now discontinued.
In the image, there are 10 little reflections of me making the exposure - on the 10 bolts. To the right of the 6th bolt, there is a person (horizontal), as well as my tripod at the center of the image.
Exposure was in the range of two to three seconds. There is no viewfinder. I have used this enough to ray-trace the approximate view. There are always surprises - in this case the beautiful lighting artifacts, due to internal camera reflections. The lighting upon the tire brand with the little highlight was purely unexpected.
