Lost in Storage - Find data zombies using Sequoia

Ever wondered where all your disk space went?

Check out SequoiaView!
It is a pretty nice visualization tool from university of Eindhoven that shows you a explorable treemap of your disk space usage. Thereby you can pretty fast identify old VM images or installers which are lying around wasting your storage.
As you can see in the image below, you just have to follow the huge blobs to find the wasted space.

Check out the homepage of the project:
