Boosters and moving objects

A friend and I are messing around with the Tubes and thing it would be a fantastic idea to have the boosters from ball race as a placeable item, alongside moving objects.

For the moving objects it could move in multiple different ways, with a length modifier and a speed modifier for the path it travels on, as well as an option to have the platforms rotate around the center area with a distance modifier on it and possibly a rotation limit to have it only rotate 1-180 degrees and back.

Would love the bumpers from Ball Race too
