The thing is, they changed the spec after the PR 1.2 Nokia update that enabled WebGL was released in June or July. In August WebGLFloatArray was renamed to Float32Array because the low-level typed array specification was broken out of WebGL and turned into a separate proposed standard, for example. So any demos you can run might be old ones that wouldn't run in the current beta browsers!
