Pattern for blanket, squares in squares

[niffer]

I'm trying to find a pattern, and if I new the name of it I'd find it much easier!
Its the kind of blanket, that you start in the middle and knit a square, and then the whole thing looks like squares in squares in squares, and each square is a different colour.
Any ideas what this might be called so i can find a pattern?
