Gijs Van Bon shows us Skryf, a robot he designed to write poetry on the ground with sand. At Dezeen:

Skryf consists of an adapted CNC milling machine on wheels, which van Bon controls with a laptop via a simple piece of software he developed.

“I can just type in text and it converts it to a code that the machine accepts,” he explains. “It writes letter by letter and in the four hours that I write per day it will write about 160 metres.”

What happens to the poetry?

“When you’re writing one [line of] text, another one is going away because people start walking through it,” he explains. “Once I’ve finished writing, I walk the same way back but it’s all destroyed. It’s ephemeral, it’s just for this moment and afterwards it’s left to the public and to the wind.”

Here is a video of Skryf taken by Gijs Van Bon:
