Finding the patterns on my journey to #IUCr2026 starting off leaving the Austron and it's beautiful pattern tiles in the user lounge 🤩💎 #BraggYourPattern

Square blue tiles with different white patterns on each- zigzags, triangles and more

A few days ago it's been confirmed that IUCr2032 will be hosted in South Korea, Incheon; walking across the wonderful Incheon airport I think crystallographers from all over the world will agree the choice is truly "spot on" 😌 #BraggYourPattern, #IUCr2032

Who's going to #IUCr2026 in Calgary? As the world's crystallographers 'assemble' in Canada - can we post some #BraggYourPattern pictures that we find on our journeys?

Reminder that one of the best #scicomm tools is still a USB microscope. #BraggYourPattern

🎉740 Crystal explorer kits sent to primary schools all over Australia and New Zealand - the last 10 will get sent out this week! Thanks to everyone who signed up for one. #BraggYourPattern

#FourierTiler already gets fans requesting options that I really had to add.. so here you go: release upgrade! github.com/stecanossa/F... New options: Log scale, non-squared FT magnitude, and export of 16-bit tiff images for those who cannot really stand small "dynamic ranges" 🗻 #BraggYourPattern

Found this pattern on a sun-dried wooden pillar on a hike today - nice educational analogue for the mosaic structure of single crystals isn't it? Such a well behaved cracking #BraggYourPattern

$A series of cracks in a wooden pillar form parallelepipeds with similar sizes, and an overall fractal structure of cracks and sub-cracks.$

We've raced past 500 schools and now well over 650! Look how spread out those locations are. We're really happy that our Crystal Explorer Kits are reaching remote primary schools all over. #BraggYourPattern

And of course now anyone can flood Bluesky with their custom patterns... add the tag #FourierTiler so people don't miss any and can find them back! And of coruse, let's saturate #Braggyourpattern as well 😏

disordered alternation of white squares tilted to the right or to the left.

total scattering pattern of the tilted squares pattern, showing sharp peaks but also diffuse bands radiating as eight broad "spikes" from the centre.

#BraggYourPattern Seoul Edition #2: a... "45° stone wall"? Not quite sure how to call it but I questioned my cartesian reference for a second... Spotted in Namsan Sky Forest trail.

A wall of square grey stones, but everything is tilted by 45° for some cool reason.

#BraggYourPattern Seoul Edition #1: it must have taken an incredible patience to make this packing masterpiece decorating Sungnyemun Gate 🌺

A wall of rectangular stones, well packed despite having all different size, larger at the bottom, gradually smaller towards the top. Many light grey, some sand-yellow with a rose hue.

Here's the latest distribution map. 53 more schools have signed up since the post below! The most recent order is from a remote school in the Pilburra (NW part of WA), somewhere down the track in the photo. The Satellite view reinforces how remote it is. They also have an #elementsets on its way!

Yes I'm the weirdo that goes to the beach for the patterns #BraggYourPattern

Image of patterns in the sand in the intertidal zone. The sandscape fills the image, and there are regular wave patterns in it. For a sense of scale there are two white shells in one of the divots in the sand.

And here we have our Fourier transform nr. 58! As far as I'm concerned, perhaps the most enigmatic and unexpected spectrum so far... anyway, quite a spectacle! #BraggYourPattern #Fouriertransform #crystallography As always, more on behance.net/specialdefects and instagram.com/specialdefects

$A square divided in four squares, each containing strands of violet-and-blue light - some like rays, some like diffuse bands - separated by darker shady regions. Overall, these lights look like refractions coming from the centre of the image, which gets darker and darker in approaching the very middle.$

Time for a new 57th entry in my #Reciprocart gallery! This time we look at the frequency spectrum of a Hyperbolic tiling of triangles 📐 Unsurprisingly (for the experienced) it's a bunch of lines... but the hexagonal symmetry is visible if one looks close enough 🧐 #crystallography #Braggyourpattern

A nearly isotropic pattern of lines irradiating from the centre. The colour scheme is a fresh combination of teal, light violet and blue on a white background.

Still making my mind up if this is a good #BraggYourPattern or not - nice nod to Escher, but sort of annoys me the colour fish are sitting above the tiled layer!

Picture shows a painting from a wall at a hotel, It depicts fish that are stylised so that they geometrically fit as tiles. Fish in the background are black and while and are tightly packet together - in front of these are similar style fish but these are coloured in - green bodies and orange fins and tails.

Someone in Verona decided to make "phonon-ish manhole covers" - Approved 👌🏻 #Braggyourpattern

A manhole cover, where dots on a square grid are smoothly deviating from the square lattice, resembling a phonon in a crystal.

When diffraction data has low resolution you can always make some Rorschach Tests out of it. #crystallography #Braggyourpattern

In case someone was wondering about the origin of those frequences... 😌 I admit this is pretty challenging to decipher in terms of real-space to reciprocal-space relationship, without knowing know how it is made. #FourierTransform #Crystallography #Braggyourpattern

An aperiodic tiling formed by the intersection of two square tilings of squares, one tilted by 43° with respect to the other. Many shapes are visible, diamonds, triangles, irregular octagons, and many other.
