Amazon has the Chromecast HDMI Streaming Media Player for $29.99. Regularly $35.00.
While not specifically a photography item, I'm a big fan of the Chromecast. I've had one since they first came out and use it all the time. I primarily use it to watch YouTube videos (like those from AdoramaTV) on my living room TV, but it can do so much more. It's definitely worth the small investment!
