One of my stalled/future projects is to add a plug-in to reveal.js, (a 2d "slide show" presentation framework), tentatively named "nthD" that extends reveal.js to as many dimensions as needed. I've got some some design notes on my github account, (that where my handle "tfer" comes from). It was originally to be based on a fork of "flowtime.js", but that has been chucked as what it did was base on a clever, but not extensible css based animation scheme. If it ever gets built, it should go well with dendron notes, each dotted level added just goes down another dimension. Multidimensional spaces are only hard to visualizes when the each dimension includes the set of Reals, not so much for finite integer sets as we are dealing with here.
