Google offers a wide variety of services: Google Buzz, G-Mail, Google Crome and Google Documents (Docs) – just to name a few. Google Docs is a service that allows you to share documents with friends and colleagues and the idea is that everyone in the group can edit the uploaded documents. This is designed to enable collaboration despite distances.
Google gave 3 people, situated in 3 different locations, 3 days to create a 450 slide presentation-animation. The animation works just like a roll of film and the graphic tools of PowerPoint are familiar – but they have been enlivened.
So if you don’t what you shall be doing over the holidays, you can pitch the idea to 2 friends that you shall attempt something similar. You can get the presentation here (but be patient, it’s a large file): http://goo.gl/6MJwH. I wish you joy of it.
