Anyone remember what these are called?

I saw a demo of these bits of kit a year or so ago...little cubes with displays on them, that you could use for literacy and numeracy. They work as a set, and have gyros in them, and you use them almost like a game to complete various tasks by putting them next to each other, turning them round, arranging them in a certain order... etc

 

I cant remember for the life of me what they were called!
