Depending on your "randomness" need, you can alter the increment of  
the sequence so it changes by a different amount than "1" on every  
increment, though it will still be constant increment.

You need to specify what the purpose of it being random is, then you  
might get more useful responses.  Does it need to be random for some  
security purpose?  If so, describe the level of security,  
specifically, against what threat are you defending?
