It’s called the eStarling and has built in Wifi so there’s no need to start tunnelling CAT5 round the fireplace (unfortunately it still needs an external power supply so it’s not totally cable free).
What I especially liked about this LCD picture frame is that you can set it up to pull pictures down from an RSS photo feed on Flickr based on your own tagged keywords. Another really cool feature is the ability to email photos directly to the frame. So next time your on holiday leave the frame in the office (turned on of course) and then whilst you’re lounging by the pool take a few pics of the more pleasant eye candy on your mobile and email it to the picture frame in the office. Hey presto your colleague are even more annoyed that your on holiday, what better way to make that holiday feel even more special :).
Available for about $250 from ThinkGeek.
