The PeRSoN.NeL iPhone App truly allows you to virtually decorate your life. With it you can decorate a link or decorate your virtual self (through the integrated Layar Reality browser). In addition you can post it to Twitter, Facebook and Foursquare so everybody can check you out.
And on top of that it has more min-e-art (even in 3D), so
N.B. If your friends don't have an iPhone, send them to the
PeRSoN.NeL layer (direct link) to see your
decoration in Augmented Reality.
A short introduction of PeRSoN.NeL in Augmented Reality can be found here.
