Making an Interactive Music Video with WebGL

Err, I was doing that with Flash 10 years ago. You might not consider flash part of "the web", but this kind of experiment, is pretty much basic and has been done ad nausea in the past.

The biggest issue being that the tooling is not here to enable people those who are more creative than technical to express themselves without coding with a text editor when it comes to using web techs.

I personally, from a creative background, would never have become a programmer if not for flash and its IDE.

So I'd say, on the contrary , the web today ( and its forced "flat" conformism ) has never been less willing to accept creative thinkers. Everything looks like everything else and somehow anything that doesn't look like the rest is considered bad or useless by UX pundits. The web ain't a creative space anymore.
