Cat Dancers are a similar toy that are fairly sturdy and simple. They are basically a REALLY long wire with a bunch of cardboard twists on the end. The wire makes them boucce in unpredictable directions and my cats absolutely adore it, but it is a toy that requires a human on the other end to make it work.
