URL embedding is something I must leave to others. I'd be starting from cold as regards Moinmoin. Maybe we should simply fall back on html? Remind me why we need anything fancier.
Voice-over I have strong feelings against. Distracting, ineffective and culturally dependent. Traditional and reassuring maybe, but only in your own mother tongue, accent and mannerisms. Nothing going for it. And I say that as an ex-lecturer (and courseware developer). Use soothing music. It's only wallpaper. And then only in a YouTube showcase, not in a serious expository text. The same goes for moving text, or "titles" as I think movie makers call them. Only good for identifying the footage, like a clapper-board. The effort to read it can distract the viewer from the object you want him/her to attend to. There will always be accompanying text. I think the purpose of animation in technical exposition is to convey spatial concepts non-verbally. Therefore verbiage is nothing but a distraction. I like your use of coloured dots. It conveys succintly that the content of a given cell doesn't matter: just the interplay between cells. If you use numbers, or even letters, the viewer wastes brain-cycles processing these before grasping they are of no importance. If you need more modal dimensions: shape and size. As regards shape, chicks and tadpoles may be slightly better than squares and circles, but one must balance being boring against being distracting. I'd err on the "boring" side to start with, and spice-up judiciously. People assume animations have got to be Loony Toons. But someone prepared to consider programming in any language, let alone J, needs an attention-span longer than a 5 year old TV watcher. The viewer may have to study the animation for quite some time to absorb its principle. Eye candy soon gets irritating. See the "grasshopper escapement" animation, halfway down in http://en.wikipedia.org/wiki/John_Harrison -and work out how it manages to be friction-free. Jiminy Cricket would soon begin to grate. Further to that example, I think continuous animation loops are good. (Though it's nice to be able to stop 'em!) Take a J primitive which is relatively simple but maybe hard for a beginner to intuit, like monadic "=" (self-classify). Not something with bells and whistles like ";:". Personally I'd like to see an animation of self-classify, because coming from APL I'm still not altogether comfy with it in my own mind. And remember the better it conveys its message, the more trivial and "obvious" it looks and the less time the viewer spends looking at it. It's why writers of public notices are always too pompous and prolix: they don't want to appear dumb. It's really quite unrewarding work, in a way.
