Mac OS X 10.6 (Snow Leopard)
This is a glsl texture filter that makes a look sort of like a tv with a decent amount of noise and static. It's not really too accurate as far as depicting what a noisy tv really looks like, but it's not too bad for a lo-fi look.
This uses the Kali fractal equation from fragmentarium, rejiggered into working in GLSL 120.
In order to get a milder look, back down on the color values. Licensed under GPL/LGPL.
(edit: .01, vert shader bugfix).
This is a conversion of a 2D system from fragmentarium, to GLSL #120, licensed under GPL/LGPL :-)
This sample composition demonstrates the CamShift object tracking method.
In this example an initial Haar detection will be performed to define the tracking area which get passed over to the CamShift tracking. The tracking results are send through a Kalman filter to stabilize and predict the object movement (e.g. when the object is covered or only partly visible).The tracking results will be constantly re-evaluated according to a given threshold and the CamShift parameters automatically adjusted.
Still a lot of work in progress and plenty to optimize...
The attached CVDetection.plugin will need to be copied to (your user folder)/Library/Graphics/Quartz Composer Plug-Ins first
I found there to be some similarities between the art of audio and video, especially in live composition. One of these is cueing.
The composition allows one to tack a movie and select up to 12 points during playback. Using the allotted keys you can revert back to these cue points at any time. This comp also supports audio.
Supplied is a video to use. I found "Apple Pro-Res 422 Proxy" to be the fastest but I would love to hear if anyone has found something that works better.
This is a speed-optimized version of the Icosahedron shader posted here: ( http://kineme.net/composition/gtoledo3/Icosahedron ).
What remains is basically the depth equation...licensed under GPL/LGPL.
To paraphrase my icosahedron post (http://kineme.net/composition/gtoledo3/Icosahedron), I was checking out the source for fragmentarium (http://syntopia.github.com/Fragmentarium/ ...licensed under GPL/LGPL ) , and setup the shaders to work in QC.
This is an Pseudo Klienian Menger fractal running in QC's glsl shader patch.
It's fairly slow, so don't expect it to be a real time thing at high quality settings. :-) It's a little snappier than the icosahedron... I'd guess it could be made to run faster by making the lighting and color routines simpler.

This composition uses Kineme2D's Bezier Path With Curve and the Grid With Bezier Path. It iterates the Bezier Path With Curve in a way that allows you to subdivide a grid by multiple beziers, and warp along the path.
(This seems to expose a slight counter-intuitive or wrong aspect of Grid With Bezier Path - as the grid is composed of more beziers, UV's shift some. In practice, this isn't a big deal, because the texture scale can be adjusted with Image Texturing Properties.)
This will need Kineme2D and Data Tools. Syphon Server is incidental, but that will be needed to for the composition to fully restore.
Tested in 10.6.
