OBSERVATIONS AND THE CODE

The code is somewhat different than my earlier PyGame creations. Further, there is a parameter 'e' to slow down the speed of the 1 Pound coin. At e = 0.98 the 1 Pound coin comes to a stop after about 141 seconds , at the upper left corner of the pygame screen. For e = 1 , the coin never comes to stop while for e > 1 , the motion becomes faster and erroneous and the software rejects it after some time.

The PyGame screen is also made to suit to that of the 20 pound note (591 x 326) and not the usual (640 x 480).

It is also worth noting that random motion is obtained without the use of the random module.
