Very funny timing this because just last night I was thinking back to the Rubik Cube craze and recalling all the different varieties you could get of them. I recalled having an ET one with pics from the film, and there was a spherical version.
Virtually everybody had one at that time, and it drove us all out of our minds! Enter young kid Patrick Bossett - think that was his name - who suddenly had a number one book on his hand on how to solve the beastly things!
So, now I know who to blame for that peculiar phenomenon! JK... you swine!
