 +      * Inkscape is scriptable via python, as I take: http://wiki.inkscape.org/wiki/index.php/PythonEffectTutorial.
 +      * May be usable for some step-by-step processing of live video footage?
 +
 +I'm espcially happy about the room-modes & schuman references, since they close the circle to something we already discussed and tried (not too successfully me thinketh) @ ICA & waves. it's a lets make it work moment :)
 +
 +I tried to compile scopeshapes for Intel, but failed so far. how would we translate the oscilloscope output?
 +
 +I'll bring two Wiimotes, but rather than waving them around i was hoping to use the IR input. lets fix diodes to Marcus' hands for his Cello performance :) OSC enabled version avlbl.
