COSC 221, FALL 2012, Programming Project #3

Distributed (initially) 10/15     Due: 10/22/2012

Using HTML and Javascript, write a page that works like a screen saver.

Make an array of objects. Each object has the url of an image, image width and image height.
After each 1000 ms, pick a different element of the array, position it at a new random location.
Do not worry about running off the right hand side or the bottom, but the upper left corner of the image must appear within the screen.

Do not erase the previous images -- you are making a screen saver.
