NCurses Disk Usage

Not quite happy with the available disk usage analyzers and looking for a fun
project to get used to C programming, I started working on ncdu: A disk usage
analyzer with an ncurses interface, aimed to be run on a remote server where
you don't have an entire gaphical setup, but have to do with a simple SSH
connection. ncdu aims to be fast, simple and easy to use, and should be able
to run in any minimal POSIX-like environment with ncurses installed.
Latest version: 1.7 (download - changes - mirror - md5 - sha1)
Requirements: A POSIX-like system and the ncurses library
Entirely written in C and available under a liberal MIT license.
Packages and ports
ncdu has been packaged for various systems already, here's a list of the ones I am aware of:
