For some inexplicable reason i’ve been remiss to post about Lukas Mathis recent piece on gestures:

In a way, gestural user interfaces are a step back, a throwback to the command line. Gestures are often not obvious and hard to discover; the user interface doesn’t tell you what you can do with an object. Instead, you have to remember which gestures you can use, the same way you had to remember the commands you could use in a command line interface.
