Like the Magic Jack, this is a 3x3x3 sliding puzzle with 26 smaller cubes. Cubes have colours red, green and yellow, and it is possible to arrange them so the entire surface is either red or green. Yellow is possible with red or green centres. IQUBE comes with a leaflet that suggests a total 12 different solution possibilities. The puzzle is suitable for the blind, since the three different colours also feel differently. I bought mine from Spielkiste (http://www.twfg.de/puzzle/default.htm). A 2x2x2 sliding puzzle is mentioned in "Rubik's Cubic Compendium", in the part that is written by David Singmaster (quote): "The only such (three dimensional moving-piece puzzle) puzzle that i know of is a sliding cube puzzle of Piet Hein which is so rare that both Rubik and I recently re-invented it before learning that it had been done by Hein." There is also an illustration which shows a 2x2x2 sliding cube puzzle similar to the small Vadasz Cube. Philip K
