The view of my computer's harddisk, produced by WinDirStat (KDirStat for Linux users). Each file is a rectangle. Each colour is a file type. Rectangle size shows file size. Top-right corner highlighted in white shows a single folder with some 4GB files.

Why have I been without this software all my life? Now I can see my computer through William Gibson's eyes.
