You can play with this pair of renderers right inside your (modern) browser:

• The team at Floored (which “creates interactive, online 3d models for real estate”) has devised cool sketch-style rendering technology.

 

• Evan Wallace has created a neat fluid simulation using WebGL (WetGL? ba-dum, tssh!). Make sure to click the water & drag around the sphere.
