vurfx (or sometimes Vurf*) is the name given to my visualisation software, available from github in the links in menus.  I've also done a few gigs and performed visuals with this rig, most notably The Cabinet of Lost Secrets at Nozstock 2017 and the 'end is here' stage at Feral Fest 2017. * from "Vurfing the Gwrx", a short story I loved as a kid
