Audio Visualizer - any recs?

Has anyone got a good recommendation for a realtime audio visualiser that works with MimoLive. Could be achieved via screen share of a standalone app or browser based?

For me it was ok if i had the opportunity to use the Preview of the Audio Monitor as a Virtual Picture Source for Programm Out (with transparencies).

Completely agree. We used a lot of Skype audio conversations in our last shows, and since we only used audio and an image, the visualisation of spectrum would be a cool detail!
