RNG Project Iterations

So I've been on a short and fruitless quest for a simple device to generate random sequences to control about 20 quad bilateral switches. (or 80 0's and or 1's) I pondered a white noise generator feeding a s/h to generate random voltages to trigger window comparators. That idea lasted 10 seconds.

Moved on to decade counters with complex clock stopping timers dividing out to banks of gates and finally the CD4066's I'm trying to switch. I may look into finally using my arduino. But in the end, I'm just not sure how this will play out. That is only one single stage of the project that is beginning to seem futile and overcomplexified.

How else can I get groups of random bits to slowly flow in and out totaling 80 switches? Well, I've just started at the drawing board.
