All you'll need for this modular origami project is ten sheets of paper in five colors and a lot of patience. The units are then assembled to create amazing geometric shapes. Set them aside grouped by color. All you'll need for this modular origami project is ten sheets of paper in five colors and a lot of patience. The Greek philosopher Plato discovered that there are only five solids with these properties. It can be constructed by arranging five tetrahedra in rotational icosahedral symmetry (I), as colored in the upper right model.It is one of five regular compounds which can be constructed from identical Platonic solids.. Here's another compound, consisting of 4 intersecting tetrahedra. Two Tetrahedra and a Sunken Cube. The Greek philosopher Plato discovered that there are only five solids with these properties. This compound consists of 5 intersecting tetrahedra. Repeat Step 1 for each set of colored squares until you have 30 strips (5 x 6 = 30 strips). Let's take a look at a couple of them.First we'll need A dodecahedron has 20 vertices, a tetrahedron has 4, thus you can inscribe 5 seperate / intersecting tetrahedra within a dodecahedron where all vertices touch....haha, that was a mouthful. Spiked Icosahedron. This figure is really a stellated octahedron. The Greek philosopher Plato discovered that there are only five solids with these properties. Icosahedron and Icosidodecahedron. Spiked Icosahedron. I wasn't that happy with my first result because the colours kept on coming out wrong—i.e. This model took me just over 2 hours to fold, and it's loads of fun! Not only can it be beautiful, but also therapeutic for the mind, body, and soul. Five intersecting tetrahedra is an interesting compound shape that has some similarities to a dodecahedron.
