Heh. A guy from the Monochom art collective put together a photographic flip-book in which he goes to a currency-exchange outlet, exchanges 50 euros to dollars, takes the result, changes that back into euros, takes that result, changes it back into dollars, and continues on and on until it’s all gone — eaten up by transaction fees. You’re sort of wondering where is this all going?, until you get to the end and the marxist hammer comes down:

“Now we have seen how that portion of the constant capital which consists of the instruments of labour, transfers to the production only a fraction of its value, while the remainder of that value continues to reside in those instruments.” (Karl Marx)

Hardly subtle — and hardly an inarguable point — but made me chuckle anyway.

(Thanks to Boing Boing for this one!)
