Doing things securely is obviously a good thing. But it rarely adds anything amusing to the thing itself.
Well, as “security” user-interfaces go, the “Shake & Share” feature on the ZeptoPad iPhone app is a rare thing. ZeptoPad lets you draw, even mind-map, on the iPhone. It has a good UI, and an amusing slightly retro, “MacOS Classic” look. And it has cut-and-paste.
“Yes, yes, all very cool. What’s so interesting about an ‘Etch-o-Sketch 2.0’ app”?
Well, it does file sharing, in obvious and easy ways, largely by importing and exporting photos. But the really cool bit, is sharing files with another ZeptoPad user. You hold the two units together in your hand, and shake them back and forth. ZeptoPad uses the accelerometers to generate a shared secret, and transfers the selected file.
And that is very cool.
A YouTube video shows the app in action, with a Shake & Share demo at the end.
