Torta shows you where your disk space is being used. Its user interface is similar to that of the awesome program filelight. Unlike filelight, Torta does not need any graphical environment to run: it analyzes the file system directly and generates a Flash file that you can load locally or remotely on any Flash-supporting web browser.
Torta uses Gordon, a library that provides flash generation functionality.
Torta was created by Sergio García and runs in Common Lisp. It has been tested under SBCL, CMUCL and Clisp but it should run in any other implementation. It uses the standard du command-line tool and has been tested on Debian GNU/Linux as well as on Solaris.
