QuickFFTSurface(m, anObject) displays the modulus of the Fourier transform of a 2d array of real numbers as the z coordinate of a surface z(x,y). The phase of the Fourier transform is mapped into the color palette of the surface. The 2d array m has to be a matrix.set f to "sin(64*x*y)+sin(x*y*x*y)" 
The colors on the surface figure the phase of the Fourier transform
