Whimsical Clocks Ch4 Kaleidoscope Clock
A Kaleidoscope works as a combination of reflections. Mirrors are typically arranged in an equilateral triangle producing multiple reflections as a symmetric pattern which changes as the triangle rotates. The apps in this collection explain how it's done, and then, of course, turn the kaleidoscope into a clock!

Euclid's Elements-Basic Constructions
These apps are taken from Book I of Euclid\\\'s Elements. Proposition 1 shows how to construct an equilateral triangle. Proposition 2 demonstrates how to create a straight line equal to a given straight line. Finally, proposition 3 teaches how to cut off a straight line that is equal to a given line from a larger line.
