It was a link to this article: YouTube Users Create Games Through Video
Basically, someone somewhere (who is now in the running to become my new person idol) has invented a way to use the annotation feature on YouTube vids to create a "pick-a-path" adventure video game. At the moment it appears to be very popular in Spanish speaking countries, but not a great deal happening in English yet. Still the idea is very very cool. Below is the embedded start point video - please note the "pick-a-path" links won't work in this, to play with that feature you'll need to go to the YouTube site (http://au.youtube.com/watch?v=BckqqsJiDUI)
Guess what I'm doing with the cyberdrama unit next year?
