WMBiff is an WindowMaker docking utility, that displays the number of read and unread messages in (usually) five mailboxes. You can also define actions to execute on new mail arrival (for example, play a sound file), [auto]fetchmail from a remote server, execute your mail reader with a mouse click, or list subject lines from unread messages.

Gyoto is a framework for computing geodesics in curved space-times. The gyoto utility program uses this framework to compute images of astronomical objects in the vicinity of compact objects (e.g. black-holes). Such images are distorted by strong gravitational lensing. The gyoto program takes a scenery description in XML format, computes this scenery using relativistic ray-tracing, and saves the result in FITS format.

shellex is supposed to be a dmenu-style launcher with a lot more features and a lot simpler design. It launches a shell (currently zsh) and shows it in a small terminal, wrapping every command with a little bit of extra magic (redirecting stdout, stderr, disowning and closing the shell) to get more typical launcher-behaviour.

GNU Xnee is a suite of programs that can record, replay and distribute user actions under the X11 environment. Think of it as a robot that can imitate the job you just did.
