To end my series of experimentations with Quartz Composer that I started 2 months ago, here is my last patch:
It’s based on the previous one and is also driven by a Berhinger BCF-2000 MIDI controller
As for the last time, I recorded a little demo to pratice my new videomaking skills (and to find a justification for buying more video gear 
):
The audio part is Dream by Paolo Lunardi (from his album Essential). I found it on Jamendo under a Creative Common BY-SA v3.0 license.
A year ago I explored visual control by plugging a generic Behringer BCF2000 MIDI controller
So here is my MIDI playground:
Nothing exceptionnal to see here. It’s just a bunch of dumb patches to control the color of the background screen and its intensity. The latter can be modulated by pulses with different profiles, and also by the sound captured by the MacBook‘s microphone. The source composition is downloadable.
Just for the sake of it, I’ve recorded a quick and dirty demo with my Canon 7D
Here is the video, which I edited with Kdenlive:
The audio is sourced from Jamendo. It’s the track One Year written by Paolo Lunardi for his album Essential, and released under a Creative Common BY-SA v3.0 license (thus making my video subject to the same license).
While playing with Quartz Composer, the only composition I made with a clear intention of using it was this one:
As you can see, it’s just my band‘s logo, subtly glowing (or breathing, as you wish). It’s a simple but effective animated stage backdrop. I haven’t used it in any of our concert, but next time a video projector is present on stage, I will ! 
As usual, here is the source composition, and a preview of the patch:
After creating a series of compositions based on my kaleidoscopic patch, I played with Quartz Composer’s particle system, to create a flame and falling snow flakes:
As for the last times, both Flame and Snow source compositions are available. Flame’s patch looks like this:
And here is Snow’s patch preview:
Here are 2 new Quartz Composer compositions. Both of them are based on the same kaleidoscope patch from my last post, but are processed before the final rendering. This gives some interesting visual effects that are quite distant to the original kaleidoscopes.
As usual, sources of this Sharp scan-lines composition are provided. And for information, its patch looks like this:
Again, you can download the Squared lava-lamp source, and here is preview of its patch:
To continue the series I initiated 2 weeks ago about my Quartz Composer experimentations, here are two other kaleidoscopic compositions:
Kaleidoscope #001 source is available, and its patch looks like this:
Again, here is Kaleidoscope #002 source, and a screenshot of its patch:
