Blocks was really clever and powerful 3d content creation tool in VR made by Google some years ago, but then was abandoned along with tools like Tilt Brush...yet they kept the bones of these tools Open Source for others to tinker with, and so, Open Blocks was born a few months ago. This rekindled my interest in content creation in VR, though I did end of modifying the scene somewhat through Silo 3d from Nevercenter.
