Here is an interactive tool by Google that lets you create and customize 3D models in virtual Reality environments. Blocks is available for Oculus Rift and HTC Vive platforms. It comes with 6 simple tools to create simple to complex models. You will be able to modify the color and other settings before exporting your work.
Users will be able to share their work via links, .obj exports, or animated GIFs. Pretty neat if you ask us. More info is available here.
