Disk Inventory X

Yesterday I stumbled on a piece of software called Disk Inventory X for Mac OS X that is pretty cool. It shows you graphically, with colored blocks, the relative size of files on your hard disk. It's unrelated to Geebis, but is a useful piece of software for finding those old Ubuntu ISOs that you've been saving up that should be deleted.

For Windows users there is a similar program called WinDirStat.
