Milk Carton - Topias Tyystjärvi, originally uploaded by Origami Weekly.

Let's take a step back from all that complex stuff and return to the simple things in life, like a cup of milk. This week we have Topsu's milk carton. A nice simplish design...but I wouldn't try filling it with milk!

Approximation of a Parabola, by Andrew Hudson, originally uploaded by Origami Weekly.

This week we've got something unusual-- a geometric model with a proof attached! This is an algorithm to produce an approximation of a parabola.

Diagrams here. For additional help, here's a youtube video showing how to extend the process a little bit.

Spinosaurus - Shuki Kato, originally uploaded by Origami Weekly.

This weekend is the Pacific Coast Origami Conference in San Francisco. Andrew and I will both be there. Since we will be having such and awesome time at the convention, I thought it would be nice to pass a little awesome onto y’all.

This is my favorite diagram of the year. Not just my favorite Origami Weekly release, but my favorite, period.

This week we present to you diagrams for Shuki Kato’s Spinosaurus.

Yes, you read that right. 130 steps.

The Spinosaurus is my favorite dinosaur, so you can imagine how thrilled I was to find these sitting in my inbox some weeks ago.

Who knew diagonal box-pleating could be so fun!

Spinosaurus - Shuki Kato

The version above was folded by me, Jared, from a 35 cm square of double MC tissue paper. It is slightly modified to have more pronounced spines, and a forward-pointing sail, as is my favorite interpretation.

Many thanks to my friend Shuki!
