• Definition & Origin: The Fig Leaf Motif (known in Arabic as زخرفة ورقة التين) is a classic stylized design widely used in Islamic geometric patterns and Arabesque art. It seamlessly blends organic, vegetal inspiration with strict mathematical structures.
• Historical Significance: This specific pattern is famously associated with Islamic architecture in Moorish Spain and North Africa, notably featured in the breathtaking tilework (Alicatado or Zellige) of the Alhambra Palace in Granada.
• Geometric Structure: Unlike standard free-form floral designs, the fig leaf motif is constructed over a rigid underlying grid. It is typically developed from an octagram (the 8-pointed star / Seal of Solomon), allowing the interlocking leaf shapes to tile the plane perfectly with no gaps or overlaps.

This is a chess variant I made, where the rules are the same as standard chess, but the board is an irregular grid. This makes rook lines bend and bishop lines fork.

So just like a standard board, every tile is still a quad. And every tile still has only 1 neighbour for every side. But it can have more than 1 neighbour sharing a corner, which is what makes bishop lines fork. Or it can have none, which is what make lines bend.

The steps to build this: - start with a plane made of triangles - pair some random triangles with their neighbour and fuse them into a quad. You end up with gaps between those quads where triangles cannot be paired - subdivide everything. Quads become 4 smaller quads. Triangles become 3 quads. This is the playable grid. - Then it's just a matter of smoothing it (in this case the points on the edges remain static, only the inside points are smoothed) and ensuring neighbours don't share the same color.

I've now printed a couple of them.

This custom Lord of the Rings themed lamp is a dual morph polyhedral that is 50% in between a pentagonal hexecontahedron and a snub dodecahedron. I used Stella4D to project a customized map of Middle Earth onto the faces and UV printed the map using the Eufymake E1. The frame parts were designed in Fusion 360 and 3D printed on a Bambu X1-C and H2S.

Hey everyone, if you're interested in what the formulas behind shells are, I have a video on my YouTube channel explaining how it works:)
