Parametric animation

Here are some examples of parametric animations created by my students. Right-click on the sliders to animate any one of the following: t1 controls a translating wheel. t2 controls a wheel whose center "bounces sideways" off of the y-axis. t3 controls a planetary motion, point that rotates around a point that rotates around a point. Individual periods are 10, 20, and 30 seconds, therefore the entire system resets at 60 seconds. t4 controls a wheel that "bops up and down" as it moves away. t5 controls a wheel falling in a "falling leaf" pattern, with gradually increasing speed and amplitude of motion. t6 controls a wheel that rises and falls quadratically. t7 controls a wheel that moves in a pendulum-like motion.
