Fences is a one-of-a-kind program, allowing you to draw labeled shaded areas on your desktop, which become movable & resizable containers for your desktop icons. These groups can help bring organization and consistency to your computer's desktop, solving the "constant mess" problem that has plagued the desktop since its inception.

Fences also helps you finally appreciate the wallpaper you have hiding behind all that clutter.
In addition to its organizing features, Fences offers a novel quick-hide feature (in-patenting-process). Double click your desktop, and all your icons will fade out. Double click again, and they'll return.

A cool desktop feature to keep your desktop clean and give it a nice modern look while keeping you organized as well, plus you can actually see your desktop (for those you have way too many icons on there desktop). Best of all, it is FREE!
