Take a look at random vs pseudo-random values (displayed in a very nice graphical way).
I wander if there is a truly random number generator out there, something portable, like a USB random generator that uses some physical phenomenon...
Options are:
- usb random number generator
- what about a CD with 600mb of truly random values? (details here) :D
- random generator based on atomic decay (here). The webpage "ticks" like a Geiger counter: scary! :>
- and here there is a web service that gives random numbers generated from the non-deterministic "quantum physical process of photonic emission in semiconductors"... GULP! The server gives values at this address: http://random.irb.hr:8000/
