Note to self: Carousel and Carousal are not synonyms, all irony aside.

I think that there may be a fourth law of thermodynamics which is specific to Carousels of Progress in particular, which means that there is a loss of generated progress upon each revolution. Er-- could have been Carousals of Progress, though, and this is only because I use the zeroth convention in numbering my laws. Maybe it is a subset of the second law. I always found thermo a bit slippery this way.
