Here’s an interesting one-liner to ponder.

0.step(100, rand) { |x| puts x }

Think of timers, for games or whatever, you could easily alter the  
pseudo-random stepping increment to make it bigger but random, or  
have broader ranges of randomness.

The interval will not be obvious to the user.

But constant. I am not sure I understand what this is good for. Can  
you share your ideas?

Kind regards
