Matt Biddulph, scary clever, has done something wonderful:
I've spent a few hours hacking on some toy objects with this new capability, starting with the mashup de rigeur: Flickr integration. My home in SL now sports a simple picture frame. Touch it and it looks up your avatar name to see what your favourite Flickr tag is, picks a random picture with that tag from Flickr and displays it on its surface. If it hasn't met you before, it asks you to tell it what tag to use.
Cute! Personalised home decor. Very cool.
It probably took him all of ten minutes, too.
