This is absolutely a wonderful project, from a very talented member of the demoscene. However, "for the first time ever" isn't entirely accurate. Web-based visual experimentation environments for 2d/3d programming have existed for years, from the Flash-based (wonderfl.net), to Java, to (many) based on processing.js. Being shader-based, I'd say this is actually less accessible to kids, unless you're just teaching them that moving sliders and changing parameters is 'programming'.
