autospa writes with an intriguing story found at Nature
about direct electrical stimulation's effect on the brain. By applying low levels of electrical current to different parts of the brain via electrodes placed on the scalp, University of New Mexico researchers claim to have documented some significant changes in brain activity
, which vary depending on the part of the brain targeted. Gamers, take note: in one experiment in which volunteers were recorded while playing a video war game, "those receiving 2 milliamps to the scalp (about one-five-hundredth the amount drawn by a 100-watt light bulb) showed twice as much improvement in the game after a short amount of training as those receiving one-twentieth the amount of current." The idea of affecting the brain by electric stimulation isn't new; but the battery-powered, non-invasive variety naturally leads some people to consider rolling their own

Pinch and open mostly mean zoom out and in, but sometimes you tap to open, sometimes double tap. Sometimes right swipe is back, som times there is a back button, sometimes you just have to go to home and navigate back down. ... Reminds me of the early days of GUIs when every application had its own menu set with different top-level menus and different placement of various functions. Made life chaos for users. We have been there, done that, and gestures are much worse. At least with a menu, you had a printed tag you could read. Gestures are all magic handshakes until you know them. Seems like the tablet community should not have to learn the value of consistency all over again."
