Pixapr is a visualization plugin for XMMS, but not regular visualization plugin. It will output REAL light show by devices controlled via parallel port. It is based on XPLSISNJASP and Palace. Pixapr stands for Pixapr Is Xplsisnjasp And Palace Reloaded.
Palace is a visualization plugin for XMMS that allows musical control of a light show connected to a PC-style parallel port. Eventually it will become a generic "real-world" device control infrastructure.
