just some software i wrote...
Open Source? Sounds interesting. Can you post an entry on what it does?
it's not open source, it takes a directory of images and randomly 'mixes' them together using a bunch of different image processing techniques i have written. 'new' pix generated images are also then fed back into the process. It uses the openframeworks as the basic framework (which in turn uses opencv for those who are familiar) which are both open source. You can control different aspects of the algorithms using keyboard commands (switching image directories, overlays, blending options, desaturation, colour addition, channel cycling etc), so it can be used to do a 'performance'. I currently have it running permanently, dumping an image every couple of minutes, and i have a separate python application using twython (a twitter API for python) that uploads the current image to my twitter account every 20 minutes - as a kind of experimental log of what it's doing. currently only runs on windows. An early version was used at a couple of STFU events 10 years ago and rendered sequences were used in Martin Hirsch's STFU documentary. I have been developing it again recently in preparation for an AudioVisual performance at 'Test Card' in Manchester.
Nice work.. OpenFrameworks is on my list of things to play with.
I think the main idea behind OpenFrameworks is that it allows you to build visual applications that can easily port between Macs and PCs. You still have to write your own code to do what you want to do, but there are a lot of helpful libraries that save you having to write all the plumbing to get you started! There are some libraries for interfacing audio and MIDI commands from input devices which i haven't looked at too deeply yet, but i'd like to get pix to 'respond' to audio signals somehow - i think this might be my next step.
the results are aesthetically rewarding. i see it as a rorschach excercise of free association.
