Color-Mixing Cube

For someone who likes a small object that keeps changing what color it is.

Oddity 1 is familiar. 5 is genuinely strange.

A two-inch acrylic cube with cyan, magenta, and yellow faces. Turn it and the overlaps become red, green, and blue.

Three reasons

  1. The color mixing is subtractive and real. There is no light bulb inside.
  2. It is hand-polished, about two inches on a side, and lives easily on a desk.
  3. The link is the Exploratorium's own cube, not a generic acrylic block.
