// In this assignment, you must produce an original sketch containing at least 20 distinct objects of at least 2 kinds of shapes.
// Each object must be unique, in shape (ellipse, rect, etc), or in color, or in size.
// Although shapes must be visible on your canvas, you may include objects which are partially out of view.
// Additionally, you must include a 2 sentence (minimum) description of your artistic intent/goal for your assignment. 

// This sketch contains two areas painted with rectangles of technically
// identical colors and transparency, but diminishing size, such that
// subsequent applications build from a dark tint of the background, to a
// stronger intensity of the rectangles' own hue. There is a slight
// "jitter" to keep the transitions from being purely mechanical, but is
// pretty much only obvious with a brighter background and greater offset
// between subsequent rectangles. The layout and colors were inspired by
// Mark Rothko, in particular "No. 14":
// http://en.wikipedia.org/wiki/File:Rothko_No_14.jpg Other color
// combinations were tried out, but this was pretty much the only layout
// attempted. Potential variations include different layouts, more
// modular code (the current "drawUpper()" and "drawLower()" routines beg
// for refactoring), and random selection from predefined palettes.
