Thinking cap lets you control cursor using brainwaves

Brainwave cap

Getting us one tiny step closer to our goal of never having to use a mouse ever again, scientists at the New York State Department of Health and State University of New York in Albany have figured out another non-invasive way for people to use their thoughts to control an onscreen cursor. It involves wearing a special thinking cap with 64 electrods on it, and so far they've gotten it to work with four different people.

P.S. - Since you're probably wondering, that pic at right shows a record of one person's thought-controlled cursor movements, with blue where they were moving the cursor more slowly, and red where they were able to move it more quickly.
