Cruising around on Fakebook, as you do, I came across a module that seemed really familiar. I am sure I have seen it elsewhere, but am not able to find it (I think it is a Bascetta variant?):
I decided to give it a whirl – nice and simple, and quick to fold, it locks nicely with a positive paper tension keeping groups of 3 together, then you group the 3-unit points into clusters of 5 and you get a nice positive curvature. Using other combinations I can imagine zero curvature (6 modules) and negative curvature (7 modules) … hence a torus is possible?.
Riffling through boxes of stuff from our kid’s Kindy years, we came across a cache of artworks my Son painted. Being too precious to throw out (and long since removed from the fridge), I set about cutting it up into 2:1 rectangles – LOTS of them:
I then arbitrarily folded them into a modified unit based on one I used that was designed by Tomoko Fuse.
As part of the Sydney Origami group’s weekly challenge, we were tasked with a modular:
This is Regenbogen, designed by Maria Vahrusheva, described in the following Youtube tutorial video
The units (you need 30 for a ball of this configuration) are quite easy to fold (I managed to teach them to my Pastoral Care group kids – their version of this fold is still a work in progress … yes, I have folded nearly 2 of these now) and luckily (for boys at least) consists of mostly folding in half – something most people can do.
I have seen amazing geometric models based on Heinz Strobl’s strip-based modular technique called “Snapology”, and thought it about time I gave it a try:
Starting simple, I divided A4 sheets lengthwise into eighths, then gridded squares on those strips. I used grey for the core, 6×1 strips were cut for each triangular core. I used red for the connectors – 4×1 strips were cut for these.
The locking mechanism is simple, and in situations where the modules are tightly packed it just sort of holds itself together, but I can see how, with small extensions to the connectors you could easily and securely lock adjacent modules more securely. Continue reading →
Assignment time at school is fairly boring, for the most part, for a teacher. Students have lots to do, you need to be available to help on demand but there is a fair bit of sitting around waiting to be needed:
I had found a bunch of PDF’s explaining briefly how to fold parts of what I had assumed would eventually be a dragon. After trial folding the head and a foot I thought it was something I could do in stages. I (arbitrarily) decided my “standard square” would be the biggest cut from an A3 page. Most parts were then made using this standard.
Origami purists would probably have issues with this design, as there is an element of paper craft in some of the details, the head, for instance, is actually 1 standard square and 6 other bits of paper, folded and (shhh) glued in place. The body was made from 7 separate standard squares, 6 of which were the same, the tail segment was a little different to create the fan end.
