Do you know about the site Flickr.com where you can put your photos onto the internet? (You can't access it from school so there is no link here but you might like to try it at home).
Now someone has come up with the idea of logging all the images which are uploaded, so you can look at a world map and see who is posting what, where, as it actually happens.
It's really interesting to watch.
It's called 'Flickr Vision'.
Things to think about:
What images are coming from what countries?
What is the time in the country where they are posting? 3am? lunchtime? bedtime?
Which parts of the world seem to be using the internet the most?
It's best to try it at home where connection is faster - that way you can see the pictures too, not just where they are coming from.
