//Choose one of the following (or create your own). Post links to results here.
// 1) If you worked on a random walker assignment from last week, redo it using vectors
// 2) Extend one of the examples into 3 dimensions.
// 3) Apply the concepts of velocity and acceleration to something other than the usual 2D motion.
// 4) Using a single primitive shape only (square, ellipse, etc.), 
// create a ÒpersonalityÓ for your object by affecting its velocity & acceleration. 
// Can you make it appear to be ÒaliveÓ and/or have intelligence? Can it interact with the mouse?
// 5) Extend one of the above examples to include multiple objects using an array or ArrayList. 
// Can these objects interact with each other somehow?
