/*This program makes a river on a sunny day 
 filled with 10 randomly placed rocks and 5 randomly place birds*/

/*This size can be changed without stuff messing up. 
 the rocks and birds are aloud to spill off the screen it looks
 natural. They can also over lap the river bank.*/

/* This program actually took a good while. The for and while commands
 confuse me some. I originally wanted to make a stick move down the
 stream, but you can't use for or while to animate so far that I know of.
 This progam was fun though.*/
