Patented by D. Rom 2004, made by elogIQ.
(plastic, left 5 inches with 1" balls, right 3.5 inches with 1" balls)

Comes in the standard 3 x 3 version (which was also made in a clear body) and the mini 2x2 version. Rotating a ball up or down makes all balls in the same column rotate the same way, and rotating a ball left or right makes all balls in the same row rotate the same way. Each ball has six colors.; the goal is to mix up the puzzle and then restore it to each side having a single color facing up. The puzzles come with solution hints, and Jaap's Page presents a solution. Here are what the reverse sides of the two puzzles look like:
