To explore the strikingly different appearance of a geometrical sculpture as its orientation changes, sculptor Arthur Silverman constructed small cardboard models; in this case, a pair of elongated tetrahedra stuck together to form a single unit.

In the computer-operated “Scrapple” system, an overhead
video camera registers the positions and shapes of the objects on the table. A
projector generates the sliding, glowing bar visible on the surface. Special
software links the moving bar with the objects. It also determines what sounds correspond
to each shape and runs the sound synthesizer.
Welcome to an occasional series devoted to "cool stuff" that I encounter while browsing the world of mathematics and computer science. I'll peek at new developments in math and its applications, and I'll revisit old puzzles, famous problems, and historic events—anything mathematical that happens to catch my eye. I hope you'll find something of value in these brief, informal forays into the world of math.
