Does anyone remember a board game from the late 80s/early 90s called EYE.
It was a board the had two plastic spirals siraling the opposite direction to each other, with one on top of the other - you could rotate them to reveal different colours of the board underneath.
I got it for Christmas when i was about 12 and never learned how to play it
as it was so bloody confusing. I think its still my mum's loft in pristine condition...
