I'm still having trouble grasping why there's a bright center ring in the Fourier transform of a blue noise sample pattern.
The noise everywhere else makes sense because there's an even distribution of frequencies in the x and y directions unlike the regular pattern which has frequencies that are all multiples of each other.

@lucida: The bright ring comes from the minimum spacing between samples; there is a peak corresponding to this minimum distance.
