Exceptionally Uncaught

I was talking today at lunch about a game I used to play. The guys who wrote it set out to make a game where hacking worked just like it does in the moives. So you can bounce your connection around the world to make it harder for people to trace you (you even get a map that shows how far along your connection the tracer has come). When you decript a file it shows random numbers that keep changing until they all lock into the right position. When you search through a social security database it flips through photos of everyone.

It's called Uplink. Mac version is here.
