I came across this entry the other week and decided to play around a bit myself with it. I don't nearly get as much time as I would like to "play" with coding these days so this was a nice escape for me.
Over on hackdiary, Matt Biddulph came up with a very cool flickr integration to Second Life the problem I had though was that I could not get it to work against his server (he even states he might shut it down if bandwidth and all of that) so I decided to do something similar to what he did...
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.

What I did though was pull a basic 10 image slide show based on a requested tag instead of the coolness that he came up with avatar aware and all of that.
The whole thing was rather easy to do and was a simple "hack" of what Matt did as well as some slight modification to "getflickr.php" from Tim Bishop and Eacosta.

You can of course come by my office in Second Life and purchase a working copy of the "flickr TV" if you like but why not just save yourself the money and DIY :-) besides you can do so much more with the code by itself :-) and I don't support it which is why the "working" copy is so expensive.
