Yeah, the graphical effect of ohmu flashed me there for a second, but in the end I did install ncdu. ncdu is my replacement for "du -sh * | gsort -h" on OSX - with extra features such as traversing through directories, seeing empty files adhoc and deleting directories/files. I don't see the advantages of ohmu, except that it looks nice.

ncdu is good and super-useful, but this omhu is not only software, it is a work of art.
