The lines of virtual and reality are slowly blurring, and soon enough we'll see something so realistic we could bring it out from the virtual world to the real one. Post it notes are making a transition from computer screen to real world.

3M worked with augmented reality developer Metaio on the new app, and it will let you pin a virtual Post-It to a real wall. The video after the break shows you can use an iPad to take a picture and you can put that message on a wall with others.

You can only see the messages on the app, and to use it you need a marker which can print out and post to a wall to begin accepting virtual Post-its. 3M introduced the tech at SXSW this week.
