Firmwareagent adds a function to the FreeBSD kernel that can be used by other modules to automatically obtain firmware images. Typically, modules incorporate firmware in their code, which causes legal issues and wastes memory. Firmwareagent addresses these problems by retreiving the firmware from the filesystem (other locations can be transparently added). It is used by the p54u driver.
Madrigal is a network-controlled real time music visualization program (i.e. VJing software). It consists of a server that runs on the computer recording the audio, rendering and displaying the visualization, and a GTK2 client (with a hildonized version available for the Nokia 770) that is used to organize visualizations and switch between them.
