What Toy Do You Miss?

One of my favorite toys was Rubik's Magic Puzzle.  Sort of a Jacob's Ladder on steroids.  It was made of 8 independent squares connected by bands that allowed the squares to move and change position relative to each other.  The object was to take the puzzle from a 2 x 4 rectangle with three rings to the image on the left.


Other configurations were possible including 3 dimensional such as loop and a "fish" (image on right).    


It was created by Ernő Rubik and came out in the 80's.  Like the cube there were speed competitions.  Below is a video showing the solution and a one-handed 2 second attempt.  I would love to have one again.
