Four Chambers is unlike any porn you've seen before - it's visceral, high art and provokes thoughtful discussion around what porn is. Celebrating their 10th year of the Four Chambers project, we talk to Vex about what inspires her filmmaking, the issue with "ethical porn" and how FourChambers came to exist.
