Relativity and photography
The theory of relativity states that the perceived speed of an object is relative to other speeds of other objects--there is no absolute speed per se.
In this case, even though the carousel is going at a nice slow speed for the kids, we can make it seem like a hellish tornado of movement by just making the camera go slower through a long exposure.
By NOT using a tripod, the nonlinearities in my muscular control lead to chaotic-like variations in the circles, which add to the organic and emergent nature of the image...
Plus, orange light is cool.
