Marbleworks Compatible S-Curve

Description

This is a part of a parent collection of many different marble tracks compatible with Marbleworks Grand Prix marble set. See remix source for larger collection of marble tracks. Why go in a boring straight line to get from one tower to another?! Instead you can now traverse a winding S-path to get from point R to T. The math involved to generate an S symbol is: ``` x(t) = t - 0.6 sin(4 t) y(t) = 1.5 sin(2 t) ``` Enjoy!
