A lot of cool technologies are coming from non-web world to Web Application Development. One of the most excited examples is WebGL [https://www.khronos.org/webgl/]. It’s a free web standard to use low-level 3D graphics right on the page via canvas element. It’s based on OpenGL ES 2.0 and has similar development approaches. To test if your web browser supports WebGL just go to http://get.webgl.org/. Almost all modern browsers and platforms support WebGL. It doesn’t need special plugin like Flash player or Unity.
