Using a custom VJ software I developed, I performed visuals at a couple of the early Nonprojects record label shows. The software I developed let me mix in a live video feed from a wireless camera which was mounted on the ceiling and pointed down at the performers.
However, after performing visuals twice, I concluded I didn't like it, and prefer performing music.
I released the software as open source on github. You can download it here: https://github.com/rchrd2/nonprojector
