Well, my father told me about a real-world application for an independent
(constant) current source, which is not exactly what you asked for, but
might be of help anyway... In the old days (before high-power halogen
lamps?) they used an arch-light in the movie projectors used in theaters.
This device consisted of a constant current source and two electrodes. To
start the thing, the electrodes were shorted and the supply switched on. The
electrodes were then moved apart and an arch formed between them. 

I also believe that and electric welder is a constant current source.
