Matters 3 has been conceived and created to provide a number of examples of interesting people doing interesting things, as a testament to the projects that are underway, but also as a charge that there is far more to be done. The intention is that the material can be dipped into as a pool of knowledge, read and reapplied as new and necessary tools in the hands of practitioners and audiences to forge new avenues for experimentation and advocacy. Matters 3 is edited by John Ward Knox.
