I've only just noticed that UnityMol has been updated.

UnityMol is a molecular viewer and prototyping platform for the Unity3D game engine developed by Marc Baaden's team in Paris. It includes HyperBalls designed to visualize molecular structures using GPU graphics card capabilities based on shaders (GLSL or Cg). It can read Protein Data Bank (PDB) files, Cytoscape networks, OpenDX maps and Wavefront OBJ meshes.

There is a UnityMol WebGl demo available http://www.baaden.ibpc.fr/umol/webgl/ which gives you a great way to explore the display options now available.
