Picture Your Disk Space with 3D Filesystem Browsers
"You don't need a Ph.D. in scientific visualization to have some fun with three-dimensional data. Whether you're searching for an unused nook in a cramped disk partition, or trying to find the bloated temp/ folder that's crashing your system, sometimes the flat folder view of a traditional GUI file browser is little help. Luckily, Linux offers a variety of 3-D filesystems that can make your disk usage statistics come alive."
