From the Gnome Usability
list:
"Season of Usability is a series of mentored student projects to
encourage students of usability, user-interface design, and interaction
design to get involved with Free/Libre/Open-Source Software (FLOSS)
projects. It offers an excellent way to gain experience in the
interdisciplinary and collaborative development of user interface
solutions in international software projects."
