I was chatting to the guys from the Centre for Alternative Technology earlier today (they're running the Bluetooth Takeaway in our field at Glastonbury) about some videos we might film about what they're up to at the festival. It seems, however, that they're already video stars in their own right, having filmed and starred in their own production, Cheat Neutral.

So, we've covered the Techno-Dome and some of the highlights in the Greenpeace field. Let's see - what else have we got lined up for Glastonbury?

If you've ever wondered what your carbon footprint looks like, you can get your own carbon calculator installed on your mobile at the Bluetooth Takeaway. The Centre for Alternative Technology will be offering them to download via Bluetooth.

Then you can stroll over to the Guardian Soulmates for some 'carbon' dating. They'll match you a mate with some speed dating and carbon mating. There'll be dancing and cabaret in the evenings between 8pm and 10pm, and if you get serious we'll 'marry' you on Sunday afternoon for a year and a day, just like in the fairy tales.
