Just to explain this example further.  I ran into this issue when trying to use arc4random to do this.  The eye is really sensitive to patterns in cases like this where it is represented visually.  I had to create my own RandomSource (see previous email) with a generator designed to make things less random (in a way that feels more random to the eye) to make this look ok.
