This uses rigid rods. Seems obvious in hindsight?

This is what I was trying to do originally, I wonder what it would look like if I used rigid rods for the edges.

Two modular origami cubes made from 1:√2 rectangles and squares (Canoe Unit 90° by me).
#origami @origami #MathArt #geometry #cube #ModularOrigami #papercraft #craft

Two origami cubes on a lilac background. Each is made from six units.
The cube on the right has two opposite vertices missing, as well as parts of the adjacent faces. The missing parts of the adjacent faces are larger on the cube on the left.
The colours of the left cube are red and white; the right cube is red and blue.

Soo, auch das Cube Fully MTB mit defekter Bremse nun bei kleinanzeigen.de

Der Preis ist durchaus verhandelbar, aber um die unflätigen Anfrager auf der genannten Plattform abzuhalten eher solide angesetzt (ggf. erhöhe ich noch, je nachdem was in den nächsten Stunden passiert).

Bremsen könnten ggf. nachgestellt werden, sind aber noch gut nutzbar.

Abzuholen in #Ofterdingen.

@mrdk @unnick This version shows how the cube/octahedron works using a rhombic dodecahedron (without scaling the bars to have constant length).

@mrdk @unnick
I'm not sure that these are related to the Jitterbug transformation.

This is my recreation of unnick's original cube/octahedron loop. I used the rhombic dodecahedron and rhombic triacontahedron for this and the previous loop. They remind me of tensegrity structures.

BTW, I made a couple of origami versions of the Jitterbug transformation many years ago. This one https://foldworks.net/wp-content/uploads/2018/06/jitterbug.pdf works better than the first version https://britishorigami.org/academic/davidpetty/origamiemporium/lam_jitterbug.htm

For years I've wanted to make an #LED #Cube - I even bought led matrix boards years ago, they been sitting in a box, just waiting. A couple of days ago I found a simple 5x5 (half cube) to print. So I printed it, finding my matrix boards, I thought, wow this thing printed too big, but it says 5x5 -- Hmmmm, so dummy me printed a 2nd, with the same results. I decided to scale it down 25% - and that worked.... Can you see the problem that took me a day to see?

3d printed 5x5 half cube case for a 5x5 led matrix

my 4x4 Led half cube matrix display.... same half cube as the 5x5 but scaled back 25%

My ★★★½ review of Cube (1997) on @letterboxd: https://boxd.it/9tW0dj #Cube #movies #films #Letterboxd #cinemastodon

boxd.itA ★★★½ review of Cube (1997)Una de mis deudas pendientes históricas... Tenemos a un señor fileteado en cubitos (je) en los primeros cinco minutos, un grupo de personajes con una dinámica cuanto menos incómoda (con sus giros sorpresa y cambios de papel) y una colección de muertes creativas con gore del bueno, traiciones, paranoia y la confirmación de las mates y la geometría como una forma del mal. Es una lástima que se desinfla un poquito tras el fortísimo arranque, y que ciertos eventos en su recta final huelen a tremendo ass pull. Y que el misterio no recibe respuestas puede verse tanto como un

For if you like 'em small and heavy 'Khong' with its 2.85 Kg and a few decimeters in size is definitely one to have to brighten up your interior.
Only one made, Khong is a box of which rectangular and angular shapes are pushed out, pulled in and cut out. Lifted on 4 small feet on 2 different angles give the impression Khong is "walking".
Through openings its top and bottom indirect light emerges
