For the 8th Gathering for Gardner, held in Atlanta, Georgia, in March 2008, Kate designed a set of 8 cubes, each with 8 colors, with the challenge of arranging them in a single row (or tower) so that all 4 long sides show all 8 colors. Huh? Eight colors on a cube? Well, see, two faces (on opposite sides) are split diagonally and share two colors. The cubes shown below are not an accurate representation of the actual color distribution.
This one-of-a-kind set was on display in the exhibit room for hands-on play, as a curiosity, not a product. At least one person did solve it. Sorry we don't know who, or we'd give kudos.
Here is the instruction sheet that was included with the display.
