I’ve been fascinated with the crazy interlocking shape models that Byriah Loper has been designing for years now.

You may have heard of the Five Interlocking Tetrahedra model before. It’s pretty popular, here’s a video showing its assembly.

I’ve tried a couple of times to put this together but I can never get the 5th one to fit in properly. If you want to try folding this model yourself you can follow the video or check out the original instructions here.

Byriah Loper’s models are on another whole level from this.

His models are already amazing but if you’re into math at all then you’ll probably enjoy these even more.

These are my top 20 favourite photos of his work. All models are designed and folded by Byriah Loper.

If you’re interested in learning more about the design and math behind these models click through to the original image on Flickr and check out the description.

He also has a book that’s available on Amazon if you’re feeling adventurous and you want to try folding some very difficult models.
