OKNO a Belgian organisation which is:

an artistic exploration of networks

seems to be a platform for facilitating the creation and diffusion of new media art. A gallery, performance area, funding body, workshop venue all in one. The site is a little text heavy and not the easiest to spend five minutes on and understand but have a look at the okno public01 page (and the pdf there) as it provides some more insight on their aims:

What if we treat everything that exists within the web of networked and non-networked creative artefacts, physical and non-physical people, actions and activities, as the material that makes up the creative artefact?

The project archives should also be explored to see some interesting and beautiful works. The installation Inside the oscillator and performances Thoughts go by air and
BO-KU-SHI-N-GU BA-GU seem particularily interesting.
