Talk about cool. Check out this story about a new Holographic Augmented Reality 3D print preview a man named Ryan Smith has created for Technical Illusions: http://3dprint.com/4272/holographic-3d-print-preview/

Technical Illusions is the company behind the castAr headset, a $1 million+ Kickstarter project from last year. Ryan uses the glasses to view a preview of his print within his makerbot replicator. It's pretty darn cool if you ask me. What do you guys think? Would you use this technology if you had it available? Check out the video below where Ryan shows off the functions of his 3D printer object previewer:
