Augmented Reality Contact Card

For couple months ago I wanted to learn some new skills in the field of web-programming. I was wondering what kind of useful web-application that could be a good start of this road. Since 2009 (and still going on at the time of writing) I have been working with Augmented Reality. So I was thinking that an Augmented Reality contact card could be a good start. This project would benefit me with learning web-programming, showing off a bit of my professional work and later have the possibility to explain other people what Augmented Reality is.
