I might be interested of having a video (or manual) analysis of cards coming through the machine.
Feed the thing stacks of individually numbered cards for several (many) hours, forward the data, and I'd happily apply some statistical analysis to see if there are predictable patterns/skew.
I probably wouldn't pay much for this, though, as 1) it's not THAT hard to design a properly random machine, so the likelihood of beating it or finding patterns is very, very small, and 2) without doing it all myself, I'm not sure I could trust the data provided anyway, at least not enough to justify a significant expenditure.
Pretty much an extremely unlikely pie-in-the-sky challenge.
