multimedia system, with Thomas Grill  (2004-2006, funded by departure).

vibrez is a pure-data– and OpenGL-based multimedia system which focuses on user-friendliness, high performance and integration of rich media and networking technologies.
The vibrez project has initiated a number of enhancements to the devel_0_39 branch of the pure data CVS, including SIMD-accelerated DSP operation, a new low-latency portaudio-based audio interface, message-based configuration of the audio and MIDI system, basic multi-threading functionality, loader hooks, and many bug fixes. The successful use of vibrez in a number of media projects has proven the underlying kernel to be readily usable and stable.
Vibrez is also used as the fundament of the cuecat CMS-based digital signage system.
