Key Design Issues
Task: Produce animated motion
Logic: We want an image to change position on the display screen to simulate movement. This will be done by moving the object incrementally when a timing event occurs.
Solution: Timing events were used for the slide show. The code will use the setInterval function to call a function that re-positions an image.
Task: Produce incremental motion: make an image move a certain amount horizontally and a certain amount vertically.
