3 parameters:
bigDisk(TNTDisk), smallDisk(TNTDisk), numberOfSteps(integer)

The more steps, the smoother the color transition from the color of bigDisk to the color of smallDisk If the smallDisk is outside bigDisk, you get a cone-like shape

//special points/components
var smallCenter = new TNTPoint(3, 3);
var smallRadius = 1;
var smallDisk = new TNTDisk(smallCenter, smallRadius, white, null);

var bigCenter = new TNTPoint(0, 0);
var bigRadius = 8;
var bigDisk = new TNTDisk(bigCenter, bigRadius, lightGray, null);
var numSteps = 50;

//TNTGraphic Objects
var myOrb = new TNTOrb(bigDisk, smallDisk, numSteps);
//for ease, reusing variables here once they were used to create the first object
bigCenter = origin;
bigRadius = 2;
bigDisk = new TNTDisk(bigCenter, bigRadius, orange, null);
smallCenter = new TNTPoint(-3, -3);
smallRadius = .5;
numSteps = 10;
smallDisk = new TNTDisk(smallCenter, smallRadius, white, null);
var myCarrotNose = new TNTOrb(bigDisk, smallDisk, numSteps);

myOrb.drawTNTOrb(context);
myCarrotNose.drawTNTOrb(context);

This shape was inspired by a student many years ago when we were trying to make images that looked more 3-dimensional.

This shape would have been impossible without our good-ole point-slope form of a line:

y - y₁ = m(x - x₁)
