whatever you do without external stimuli it will be pseudo random. for instance, a sequence of 1,2,3,4,5... is possible in a true random function.

what is a "good" pseudo random generator? who knows.

Since any sequence is possible as a result of true randomness, how can you determine the "quality" of a pseudo random generator?

These are philosophical more than techical musings, but neverthelless relevant.

If you scan this forum you will find much code that (although not supposed to) generates pseudorandom sequences :) (could not help that one, sorry).

In my opinion, the very best simple random generator is a free running timer that is read on some non-syncronous event such as a keypress. An example of this is an electronic slot machine. It has a very fast counter that is interrupted by the players activation of the "start" mechanism.
