The Big Melt WWF

Graffiti. Tech. Nature. iris Amsterdam with GreenGraffiti created these ice QR codes before the canals melted in Amsterdam. The ice was melting, so came an opportune time to remind people about climate change. The environmentally-friendly QR codes (made from sticky sand)  placed on Amsterdam’s canals contained a link to the WWF site which had info on the melting ice caps. Once temperatures warmed up and the ice started melting, the message was clear. There was no media spend, and there are no laws against printing on ice. All very environmentally friendly.
