Hi, I'm still here! I got a bit sidetracked there with a potential job offer that didn't pan out and writing some PR's for othe projects that never got merged for various reasons (never doing that again!)
But the biggest distraction for me has been getting the VR stuff up and running again, and with WebVR I hope to be adding some optional VR to this online demo/experiment/whatever-it-is too soon(ish).
