Cube
Cube is one of only five Platonic solids. This is a regular polyhedron with 8 vertices, 12 edges, and 6 faces. All faces are square and at every vertex meet three faces and three edges.
Drag the mouse to rotate the cube. Use the right button to remove and put back individual faces.
(Acknowledgement: I have learned most of Java details from the implementation by Meiko Rachimow.)
The other Platonic solids are tetrahedron, octahedron, dodecahedron, icosahedron. With 6 faces, 12 edges, and 8 vertices a cube confirms to the Euler's theorem: 6 - 12 + 8 = 2.
