I have a few short videos on YouTube. I plan to add more.

This is a 15-minute demonstration of scoring, cutting and folding a simple Ullagami model. Start to finish.


It's not always obvious from still photos that all my models are designed to fold up, collapsing flat on their faces.

Here's a very quick video of a converter script I wrote, to convert my models from rectangular to polar coordinates.
