3-D On Your Laptop

Video games have used 3-D modeling for years, but usually the only benefit you see is realistic depth and shadows on a 2-D monitor. Sharp's Actius RD3D Notebook ($2,999; sharp3d.com ) processes the same game data into 3-D images, viewable without funny glasses thanks to a special LCD display. How it works: half of the pixels on the 15-in. screen are aimed at your left eye and half at your right, producing a stereo effect. But don't get too excited while playing: the 3-D looks best when you hold your head still about 20 inches from the screen.
