A great read. Not for Bret’s slightly extreme views of the current state of touch interfaces, but for the deep understanding and insightful explanation of how we interact with the world. Made me think. It’s worth reading the whole thing.

What can you do with a Picture Under Glass? You can slide it.

That’s the fundamental gesture in this technology. Sliding a finger along a flat surface.

There is almost nothing in the natural world that we manipulate in this way.

That’s pretty much all I can think of.
