Nearly fifty-five years after the personal computer revolution, our ways of interacting with and within computational mediums — the actual atomic gestures, the clicking, the scrolling, the dragging-and-dropping — have barely evolved. As Alan Kay, whose work at Xerox PARC instigated that revolution more than anyone else, put it: “The computer revolution hasn't happened yet.” That line is now entering its third decade of being correct.

We are still, by and large, shuffling windows to and fro, seeing what we get instead of what we might mean. But something has changed. Not the interactions — the interlocutor.

Arrange interactions along these axes and something remarkable happens: you start to see the gaps. The combinations no one has tried. The territory between what we have and what we could have.
