"Funky looking" ? Hmm. You seem to be describing a symmetric unimodal
distribution; if indeed you were computing z = x times y for uniform
x and y with identical ranges, I do not see how you could obtain
symmetry in the result unless x (and y) were uniform (-a,+a).
If x and y were everywhere positive, the distribution of z would be
positively skewed, I believe.
