C Sharp: ScreenSaver Example

This is the ScreenSaver example partial code. To get the complete program working, you need to watch the youtube video.
There are many things you can change to practice. You can change the interval of the timer to make it faster. For instance: timer1.Interval=100; will make it move very fast. Also, instead of the images changes by clicking you can make it change after each position (top, center, bottom) and so on. The possibilities are endless.
