This is a very early version of WallCutter, one of the first Windows applications I've ever made.

WallCutter is designed to make wallpaper that looks good on multiple monitors. I'm having difficulty finding words right now that describe this. But basically, my program will slice out the parts of the image that are BETWEEN monitors so that the final result on your display looks "seamless."

In this screenshot, taken from my work setup, the box on the left is my 2nd monitor (19.5") and the box on the right is my laptop monitor. Ironically, the laptop monitor is higher resolution than the secondary monitor. My program will account for this when it slices up the picture for wallpaper-display.

If you think this is a cool idea, I could really use encouragement in the form of comments below. I'm having trouble finding time to work on this. Thanks!
