A scottish Tartan pattern made of red, yellow, white and blue stripey bands on a dark green background.
Squared Fourier transformed pattern from the Tartan motif, showing the absence of a mm or higher symmetry.
It's been a while since I posted #FourierTransforms, so thought I would risk getting bored with some periodic tilings... until I've found a nice case of #pseudosymmetry in a Tartan pattern 🧐 Can you spot its origin? (pun intended) #crystallography
