The README should list projects using regl.

[Erkaman]

In addition to providing a gallery of examples, I think it would be good if we provided a list of awesome projects using regl. Some projects we could add to this list are:

• https://github.com/Erkaman/wireframe-world
• https://github.com/realazthat/glsl-sat
• https://github.com/rreusser/regl-smooth-life
• http://fivethirtyeight.com/features/gun-deaths/
• https://github.com/dfcreative/gl-fourier

If anyone knows any more projects, please add them here!

Also a note here: We should add an invitation so that people can submit PRs with their own projects.
