Simply select the Open bang/button of either of the Drancel RGB GUIs.

Two Drancel RGB monitors are displayed side-by-side in one window as GEM can't (yet) seem to handle multiple windows .

These visual monitors are your very good accelerometer air music friends, experiment with your WiiTM Remote controllers until you can isolate each axis, and understand the relationship to "static" gravity and "dynamic" acceleration. Try just rotating each WiiTM Remote various ways gently, not striking forcefully. They are quite sensitive !

These visuals are designed to be projected at 1280x960, you might have trouble fitting both these and the DranceWare.pd skin on one display at once.
I usually put the GEM visuals on a data projector display and the DranceWare.pd skin on my LCD MacBook Pro screen (with display mirroring off).
