On one hand you make public on Twitter what you are doing at the moment, and on the other hand you upload your favorite photos on Flickr.
On the Twittervision site, you can watch and read live all the latest messages that are coming from Twitter, on a Google World Map.
And similarly on the Flickrvision site, you can view live all latest uploaded photos from Flickr, on a Google World Map.
Twittervision might sound a bit pointless if you are not really into Twitter.
However the Flickrvision concept is really exciting, and you could watch it every now and then.
