| A flexagon is a strip of paper folded up, which you can "flex" to reveal hidden faces. There are two types - hexaflexagons, which look like hexagons (six sides), and tetraflexagons, which look like squares (four sides). Zipped files (for Windows) to download with templates and instructions, or online instructions for Trihexaflexagon (3 faces); Tetrahexaflexagon (4 faces); Pentahexaflexagon (5 faces); and Hexahexaflexagon (6 faces). Some theory and a Java 3D simulation, and links to Internet resources are supplied. | |
