This compound polyhedron is also a stellation of the regular icosahedron. It was first described by Edmund Hess in 1876.

"Dev Harlan is a multidisciplinary artist whose hybrid practice combines the physical and the virtual with the use of sculpture, light and projection. As a self educated Artist, Designer and CG Director, Dev's uniquely identifiable aesthetic language and reductionist approach place his work at the forefront of a new mode of media arts practice."

"We looked at playing card constructions before in this column, but this one by Nick Sayers is impressively intricate. The 270 playing cards each have four slits, and lock together like the classic IQ Lamp. Each card is forced into a curved form because it locks with a neighboring card at two points which are closer together than a card’s width. Light from an internal lamp escapes dramatically from under these curves."
"The following 3D linkage effectively turns the edge skeleton of a truncated tetrahedron "inside out". Turning a polyhedron inside out is similar to reflecting it through a plane, except that the inside/outside orientation of the faces is also inverted.
The animated GIF is 10 megabytes, so it may take a while to load in full; then it should animate fairly quickly. The animation was raytraced with POV-ray by Erik Demaine."
"When a vertical water jet strikes a circular horizontal impactor, the water is deflected into a horizontal sheet. At sufficiently high speeds, the flow results in a circular water sheet, whose radius is set by a balance between inertial and curvature forces."
