General Magic Documentary (2025-02-21)The General Magic documentary is the tale of General Magic, a seminal technology company that endeavored to create the first smartphone-like device back in the early 1990s. The company started with former Apple employees such as Marc Porat, Andy Hertzfeld, and Bill Atkinson, who wanted to build a elegant personal communicator far ahead of its
Cloud Channels and Cybernetics – Data Economy (2025-02-20)Yesterday, I got my first internship interview experience, which was at a data economy company. Most of the interview meeting was actually the interviewer explaining the business model, as many of it was new to me. Here is what I understood from the meeting: Put simply, the company aims to give people ownership of their
Tessellation Rules (2024-12-10)I think the formula for the number of foldable tessellation possible given a specific grid (m x n): (m^(2mn-m-n))(n^(2mn-m-mn)) Additionally foldable tessellations can be composed of units with identical geometric patterns that are tessellated. Another option, which involves geometric gradients:
Degree 3 Shapes (2024-12-09)Degree 3 shapes intersect the x-axis at a maximum of three points
2D Crystallographic Symmetry (1) (2024-11-12)2D crystallographic symmetry is a way of describing patterns of symmetry in two-dimensional crystalline structures. A crystalline is a solid material with a highly ordered microscopic structure. At a larger scale, crystalline structures could also be tiles or wallpapers – patterns that repeat in a plane, maintaining its structure and orientation. In 2D, symmetry operations
Computational/Geometrical Miura-Ori Research Ideas (2024-10-13)Some potential computational/geometrical Miura-Ori related research prompts:
Poisson's Ratio and Miura Ori (2024-08-01)The Miura Ori tessellation has a negative Poisson's ratio — it widens when stretched longitudinally, unlike most materials.
2020 Abstract Stick Figure (2024-07-28)As a challenge to experiment with 15 and 30 degree angles, I came up with the "stick figure". To my surprise, on my first test fold, the model was exactly what I was aiming for. I think what satisfied me the most was the proportions. It is approximately 1/8 head, 3/8 body, and 4/8 legs,
2024 Ant 1.0 (2024-07-28)My first design using box pleating techniques. I got some help with the level shifters from Plant Physiologist's Youtube tutorials. I treated my paper with MC and used a small cleaning cloth to gently push the air bubbles out, while absorbing the access MC. Much less wrinkles after all. A lot of practice paper has
2024 Sea Lion (2024-07-28)I gave it a shot to design a sea lion since there are relatively fewer appendages. Being able to accurately interpret proportions is one of the hardest parts for me. By changing the proportion, it got iterated for 2 times for now This design went through two main irritations before the final result. Here is the
Kresling fold (2024-02-23)Developed by Biruta Kresling, Paris-based architect and researcher on folded structures. The pattern is the result of the natural warping of paper from torsional load. Kresling shows how this warping could be used through an experiment with cylinders and paper. She found that after wrapping the paper around the two cylinders and subjecting them to
Mars fold vs Kao fold (2024-01-21)Expanding from conventional figurative designs to investigating mathematical properties. Barreto's ‘Mars’. Mountain folds are indicated by solid lines and valley folds by dashed lines. Fold lines of the same colour have the same fold angle. (a) Fold pattern, (b) partially folded position, and (c) mostly folded position. It is based on squares and rhombuses lying
Tetrahedral Origami Antenna (2023-12-23)It is made from standard paper glued to thin copper sheets. The resulted material is 0.25 mm thick, and is folded into water bomb bases, which interlock with each other, forming a tetrahedron. There is also a reflector and two strip detectors, both of which are attached to one side of the tetrahedron. The antenna
The Maekawa Theorem (2023-11-18)The Maekawa Theorem, named after Jun Maekawa, tells us that in flat-folded origami, the difference between the number of mountain and valley creases at any vertex is always two. This is what enables origami pieces to be flattened. To visualize this principle, one can unfold a flat-folded origami piece and color alternating sections around a
