Shameless plug: If you are interested in Fourier Transform and signal processing you might enjoy my somewhat artistic 3D visualisation of the fourier transform as well as the fractional fourier transform [1]

(Fractional fourier transform on the top face of the cube)

And for short time fourier transform showing how a filter kernel is shiftes across the signal. [2]
