Building on top of lots of modules provided by Mikola Lysenko (https://npmjs.org/search?q=gl-), Hugh Kennedy shows off what today's browsers are capable of using WebGL.

Lots of support c

On a somewhat silly but related note:

A game I wrote a while ago uses GLSL, geometry shaders and transform-feedback to simulate and render a large number of particles. The particles can be dynamically created, bounce on the height-map and fade and die after some time.

Last I checked, you can easily render 350,000 particles with several viewports on my HD7970. Although the amount of hearts on the screen is a bit too much at that point.
