With Firefox 10 WebGL works and there for also Google Street View works without the need of Flash. Yes, another dependency on Flash has been removed. The previous major dependency was YouTube, but as some may have noticed they also are in a transition from Flash to HTML5 video where you get the HTML5 variant when Flash doesn’t work.
As more and more websites switch from a Flash-player for video toward HTML5 in under a year it makes you wonder what WebGL is going to change. Was HTML5 a year ago only for the geeks and cutting edge, now more and more starts to depend on it. With HTML5 Canvas a lot of Arcade games where rewritten to run in a webbrowser. With WebGL the question comes when Doom has been rewritten to run in a webbrowser. Maybe something for a Google Summer of Code project?
