What do you get if you you mash up two of the hottest web services out there, Twitter and Flickr, with television? The answer is Twittervision and Flickrvision. The Adobe Systems software developer Chris Bailey has taken it one step further and created Visionary Saver, a MacOS X screen saver using both Twittervision and Flickrvision. I have installed it and it is really neat. Thanks to Laughing Squid for bringing all of this to my attention.
