Useful Origami Resources

Here are some links to resources I have found useful when doing mathematical origami – Some great videos from the Millennium Mathematics Project in Cambridge showing how to make some simple modular origami models – lovely set of instructions for making a dodecahedron from A4 paper – the Mathigon website has lots of gorgeous pictures of origami models together with instructions for how to make them, including the Five Intersecting Tetrahedra I blogged about here. – instructions for my favourite modular origami unit, the Sonobe module – an article explaining how origami can be used to trisect an angle, which is impossible using standard straight edge and compass techniques
