What toy is this?

Question

I recently found this old toy I used to mess with as a kid, but I can't remember what it was called. It's a wooden puzzle with 4 blocks. Each block has different colored dots on each side, they are different combination's of red, blue, green, and yellow. Now, the idea of the puzzle is to put the blocks in a certain order inside this hollowed out rectangle, so that each side of the rectangle has only one color on it. Any idea of what it is called?

No I never saw it or played with one of those. sounds like a cool toy,  it reminds of a Rubik's cube kinda.  I got to get off the computer for a while.  My poor old brain is overheating again.
