I stumbled over a technology from Amsterdam called Layar today, launched in 2009. Essentially it allows anyone to scan a picture, object or printed page and see it come alive on their phones. This technology is great for magazines wanting to expand their advertising opportunities.

For a recent project in our graduate program we used this technology to show our presentation. You can view a video of how we did that here:
