Eirik Solheim is an amazing geek and CC activist at NRK, the Norwegian public broadcaster. He writes, "We filmed a train ride four times. One time for each season; winter, spring, summer and autumn. Then we used an accurate GPS-track to sync the four videos using some clever programming in combination with after effects. Giving us endless possibilities for spectacular video footage. You can watch it on the web, but we have also made it available for everyone to download in full HD -- and licensed it with Creative Commons so that you can edit, remix and share!"
