Hi Danny, WebGL is kind of the "new hotness" at the moment. But it has very spotty support in browsers, no support in IE and not in a lot of other places as well:
It's not really something that would work to use in MoI anyway since MoI works as a regular desktop application and is not set up to run totally inside of a browser. Running everything inside of the browser would either involve a huge port of all back-end program code to JavaScript or a major move to run "in the cloud". Either one of those would be a major many-years long experiment and so not likely to happen, and I think that MoI is more suited to be a regular desktop app anyway.
