Normally distributed random deviates.

[Borodog]

So to answer Sklansky's question about horse races, I wrote a program to generate normally distributed random deviates using the Box-Muller Transform:

Where a and b are uniformly distributed over (0,1] and c is the normally disctributed random deviate.

For kicks I plotted c vs c', where c' is the same deviate, except with a and b switched. I got this result:

I have no idea what this means, but it looks pretty cool. Anybody able to explain this?
