During London Design Festival 2010 Chalkyvan, the sustainable, chalking camper, will be touring town visiting Festival highlights, sustainable design events and exhibitions - adding a [re]design filter to the Festival through interactive happenings, discussions and much chalking! Fuelled on old chip fat and powered by the sun Chalkyvan, will carve a sustainable trail through LDF, which you can follow on our interactive map. Get involved, come and find us, and have your say via CHALKYVAN on Twitter.
