Small angle scattering demonstration using hairs in laserlight! Part 1by drheaddamage1,692 views
I would have liked to see a quasiperiodic structure like a penrose tiling. that might have been interesting.

@htomerif You must be a diffractionist :). structures like that are easily FT'd though, although the result may be less than revealing as the DFT/FFT used here assumes periodicity over the image boundaries.
If you have Python, and an image of one of the quasicrystalline structures, and you need some help to get the FFT to give you sensible results, let me know!
