FerrisWheel-NoDots.htm and FerrisWheelWithDots.htm
A pair of animations of the side-view of a double ferris wheel showing the path taken by a passenger as he travels around the ferris wheel. The first animation just shows the wheel turning, while the second animation leaves "tracer" dots behind in the path of the rider showing the path taken. This is used in conjunction with "Trig in the Real World", and parametric equations.

BoxProblem.htm or BoxProblem.exe or BoxProblem.mov
An animation showing three identical size sheets of cardboard folding into three open-top boxes, each with different bottom and side dimensions. This is used to show how the various size squares give different volumes of space inside, although they are made from the same size of raw material. Also there is an optimum volume which can be reached using any one size of raw material (a Max/Min problem for Calculus or below).
