s3d is a 3d network display server which can be used as 3d desktop environment.

OpenMX (Open source package for Material eXplorer) is a program package for nano-scale material simulations based on density functional theories (DFT), norm-conserving pseudopotentials and pseudo-atomic localized basis functions. Since the code is designed for the realization of large-scale ab initio calculations on parallel computers, it is anticipated that OpenMX can be a useful and powerful tool for nano-scale material sciences in a wide variety of systems such as biomaterials, carbon nanotubes, magnetic materials, and nanoscale conductors.

Grid-based manual tiling window manager with a strong focus on easy but customizable look and feel.

apt-forktracer tries to alleviate the problem that APT stops tracking official versions of a package after you pin it or install a newer version.
