LG's pinched Layar's idea and made it 3D, though I suppose Wikitude is partly to blame/thank too. They're calling it the world's first 3D AR browser, and it'll only be available on LG's Optimus 3D phone for starters.
3D? Terribly lame when it's tossed into devices as a bullet point feature. Making stuff in 3D yourself? Almost always cooler than you think. Trimensional for iPhone takes a picture of your face and maps your mug in a 3D model. You wouldn't think it but it's kinda creepy seeing your face in 3D.
