I don't think I've posted much about specific software programs, but there are a number of infographic programs that anyone can use. These two are programs that analyze what's on your hard drive, and show it you in a treemap display.

The one above is Disk Inventory X for the Mac (which I use), and the one below is WinDirStat for Windows. Both are free, and are real-life examples of how you can use infographics in your life. So take a minute, and clean off some of that old junk taking up space on your hard drive.
