   <b>Prof WM Harris,</b></a> using the random function with events to color/weight a line<br/>
  <b>How</b> to use the random function with events to color/ weight a line
	dependent on mouse location, left mouse button clicks, character key types, and
	random key releases.<br/>
  <b>Functions</b> are created for both the canvas set up as well as the creation of
	the line. Depending on the action taken by the user the line can
	vary in width and color. Left mouse button clicks result in a color
	change to blue, while the typing of any character key will change
	the color to turquoise, each resulting in a variable stroke weight;
	the width of the former will be between 0 – 1 while the width of
	the latter will be 0 – 5. The release of any key will result in a
  random hue, saturation, and brightness change to the line.
