New puzzles: Bioluminescence and Ocean Tapestry

Every holiday season we release new puzzles, this year our new puzzles feature art by Franz Anthony, a scientific illustrator whose work I’ve been following for a long time.

Crafting Radiolaria Sculptures – from microscopic life to art

https://invidious.privacyredirect.com/watch?v=Pti1uavUIG4

We’ve created a set of 4 limited edition Radiolarian sculptures that are now available in our shop. These limited edition sculptures are inspired by Radiolaria, microscopic unicellular sea creatures that create skeletons from silica. Their skeletons are among the most beautiful and complex natural microstructures, resembling elaborate filigree or latticework. Artists like us have long been fascinated by Radiolaria dating back to Ernst Haeckel’s drawings in the late 19th century. We studied his drawings alongside scanning electron microscope images to create a series Radiolaria-inspired sculptures exploring their diversity of form.

The video above goes over the process of creating the...

Meet the Flummoxagon

https://player.vimeo.com/video/1124590990?dnt=1

We’re excited to announce Flummoxagon, a new geometric puzzle game that might just leave you flummoxed. Imagine a mash-up of Pentominoes and Sudoku. Your goal is to fit all the pieces into the hexagon frame but there’s a twist, pieces of the same color can’t touch.  

It’s a fiendishly fun mix of Tetris-style block packing and logic-based constraint solving. The game ships with 13 gameboards, featuring puzzles from beginner to advanced, and new boards are added weekly to our website.

You can buy Flummoxagon now in our shop for $45. For the first month, take 20% off with the coupon code FLUMMOX...

Casa Tobi in Oaxaca by Espacio 18 Arquitectura

Casa Tobi by Espacio 18 Arquitectura is a study in contrasts, a house that finds its character in the tension between solidity and openness. The project, known as Harte Schale, weicher Kern (hard shell, soft core), sits on a steep site in Oaxaca where the Pacific coast meets rugged hillside.

From a distance the structure looks like a monolith, heavy with raw concrete, its surfaces textured in sandy tones that feel weathered by salt and wind. Step closer and the architecture begins to loosen, revealing circulation paths, courtyards and voids that soften the severity of its shell.

The topography dictated the...

Jaç Hi-Fi Café, Barcelona

On Barcelona’s Avinguda Diagonal, Jaç Hi-Fi Café brings together two parallel rituals: listening and drinking. It is the creation of Ligia and Arnau, who set out to craft a space where sound and taste share equal importance. Their inspiration comes from the Japanese jazz kissa, venues where vinyl takes precedence and conversation slips into the background. At Jaç the tradition is reinterpreted through a Mediterranean lens, making the atmosphere warmer, brighter, and more open while keeping the same reverence for music.

The interior is by Isern Serra Studio, whose work across Barcelona is marked by an ability to reduce, refine, and...
