Origami Lizard On Book

Origami Lizard on Book

I took this quite some time ago. The book was lying on my desk, I don’t remember the specific reason I needed it at the time.
I thought I’d also prepare the instructions for this critter – they are quite easy and yield this nice lizard/dinosaur thingy. When I first created this fold, I thought it was quite an achievement to make it with four legs.

In any case, it came out a very nice image. I find it amusing that in the book I’m currently reading, there are mentions of computational origami as a prerequisite of transcendence.

Exam is Done

A few hours ago, I had my exam in functional analysis. This should be the last exam for the semester.
Now I should have more time for my projects.

Currently on my radar: a startup, diStorm, and maybe a website. Of course, I expect the startup to eat a lot of my time. For now I’ll just have to see how it goes.

On another subject, I wanted to show instructions for the origrami lottery-spider. It turns out that this fold is modular in the sense that a piece of 1:n paper generates a critter with n+1 pairs of legs.
Here’s a proof of concept with a ratio of 1:8 (click for a larger version):

I’ll be making the instructions as soon as I get new batteries for my camera, and some spare time. (The caterpillar ate my batteries, along with my functional analysis books.)

Back From the Dead

As you can see, the website is back online, and I hope it stays that way.
Cheers go to Randy and James, for fixing the server.

I’ve been doing various things lately, including work on Vial and various university tests. I’ll be sure to write some more now that the website is back online, to make up for the lost time.

I also had a job interview in Tel Aviv a few days ago. Here’s a little critter I folded on the train (click for larger images):

This one is made from a square piece of paper, and it has 6 legs.

After working on it, I managed to reverse engineer my origami rhino fold. Here’s how it’s going to look:

Origami Rhino

To reverse engineer it, I had to open my original fold, and try to reproduce the fold, a bit like working on a crease pattern. I did my first version on some draft paper, so now I have a total of three rhinos. I even managed to take a photo of them playing with each other, national geographic style (may be considered nsfw). Expect to see full instructions for the rhino sometime soon.

Some time ago, along with the newspaper, came a lottery ticket. Believing that gambling is a form of taxation for fools, it was just lying around. Then one day I discovered it has a ratio of exactly 3/1. I decided to try something new, and came up with the following creation, which I dub, ‘lottery spider’. It has a venomous, addictive sting, beware!

Folding an origami swan

I believe the swan is one of the most common origami folds. I think that almost every origami book has instructions for a swan.

Well, I was playing around with the standard crane (the wing flapping bird), and came upon this thing:

The idea behind it is pretty simple. Get to the crane, unfold the back part, and reverse fold up, and align with the wings. I can upload pictorial instructions if anyone is interested.

New origami bug fold

While playing a little bit with paper, I started playing with the water bomb base. I then moved into the frog-base (I think) whice has some potential for bugs: 4 long limbs, elongated body, and four shorter flaps.

Here are the results:

These two critters look moderately bug-like. Note that the left one has these two fins at the side – those are two of the flaps. One other is the head.

I had another piece of paper which is now fubar (folded up beyond all recognition) of the same fold, which resembled a human being. I’ll probably be playing with this fold some more, while looking for minimum cuts (in graphs) and writing a compiler (for cpl).

I fold

Just some general stuff I folded while working. A pig, a sphinx, and a six legged thing.

The question still remains, what’s easier, the sphinx or the pig. Both are really simple folds. I reckon the sphinx is easier. However, the six legged thing, while complicated, doesn’t resemble anything I know, and I couldn’t figure out how to make it look like something. This just goes to show, yet again, that less is more.
