We've previously written about 'reverse graffiti' and 'living billboards', and we're familiar with 'guerilla gardening' and 'knit graffiti' but have you heard of moss graffiti? The latest in street art projects aiming to enrich derelict urban spaces is cleverly named Mossenger and is the brainchild of London-based artist Anna Garforth.
Anna's project uses biodegradable ingredients to attach moss letters to walls to spell out poems. How wonderful isn't that? The poem you can see on these pictures are by Eleanor Stevens and will be featured in four parts - each sentence is to be displayed somewhere in London.
Have you spotted any other green street art projects where you live?
If you see Anna's work when you're out and about in London tweet us @Hippyshopper as we'd love to see more!
