I recently made a demo scene for the SIGGRAPH 2017 WebGL conference put on by Khronos in L.A. last week. There were sections other than WebGL, like OpenCL, glTF, Vulkan as well. I understand from Ken Russell that it was shown at the start.
A little of a departure from the many test / QA, & development Tool scenes for QI that I have been doing. I have 3 more of those close to done to close out 1.1 release. Always go to do a "real" scene here and there.
