<p>Step inside. This is the counter you'd have found in a 1990 mall next to the Sharper Image — if the Sharper Image sold arcade parts. Everything here is a working demo of something nobody else has built yet: joysticks that tap back, trackballs that glow from the inside out, a spinning globe that paints a real 3D image in mid-air. Some of it ships next month. Some of it is still on the bench. All of it is the arcade of the future, being built by hand, right now.</p>
