I just have to post this story about a new billboard campaign in New Zealand to encourage drivers to ‘drive to the conditions’. It’s a visual treat (and one not without its critics…of course.)

The liquid transforms the faces on the billboard from innocent to blood-stained to illustrate the dangers of ignoring wet road conditions. Full story on stuff.co.nz
The boards, three of which have been installed beside Papakura and Franklin District Council roads, are designed to ooze a red biodegradable food dye as soon as it starts raining.
The red dye is then collected in a tray to be pumped back through the system. Full story at nzherald.co.nz
