When I hear the word "Random", I get nervous.

One version of "Random" actually means "Unpredictable".  Thermal
noise, radioactive decay.. Useful for cryptographic one time pads.
The other actually means "Gaussian".  PN sequence, etc.

For a dice app, I'd use a long PN generator clocked on each iteration
through the main loop (or idle) and then grab the output whenever the
dice are "rolled", such that the register is clocked far more
frequently than it is used.
