Back to the 80's :)
You can create some loops with this for your backgrounds.
Normal & audio reactive (travel speed) & Image generator versions included for use in Coge & VDMX (may need some tweaks for audio I did not check it out).
Also posterized colors & offset colors versions included.
Requirements : Steve's reinterpret 3D Object node (download here) because the stock wireframe shader ignores lightning.
Looking at a few loopback apps, capturing the audio stream from a specific application seems to be possible. Would it be a lot of effort to get this feature in Vuo as well? Without an external audio interface, capturing/loopback interfaces are by far the biggest pita when it comes to implementing audio reactiveness in the compositions. I usually hook up an external device when performing with the compositions, but for programming I'm just too lazy to set it up/don't have it at home (it is also difficult enough balancing the laptop on my lap when travelling by boat).
