It's been awhile since we've heard from the gang at IO2 Technology (they developed the Heliodisplay, which projects floating images into thin air), but now they're back with a revamped Heliodisplay they're dubbing the M3. The new "displays" are looking to march their way into the mainstream world, now that they can project images into spaces as big as 30-inches. They also provide better brightness/clarity, a higher 1,024x768 resolution, and widescreen aspect ratios. Prices are still over the top, however, coming in at $18,100. Check out the video after the jump.
