My Edinburgh: Sheriff Blobby, 34, and Mr Blob, 25, both artists

"The G8 is destroying the earth, making war, poverty, famine and making a mess of the world. I’m in Edinburgh because I want to show I’m against that and I want to do something good,” says Sheriff Blobby.

His colleague Mr Blob says: “The G8 leaders claim they are here to talk about poverty and climate change, when they're the ones causing it. It's just a facade.”

Both agree today's march is inspiring. “We’re here to have fun and also be around lots of positive people," says Mr Blob.
