Skryft, by the artist Gijs van Bon, is a robot that slowly, meticulously writes on the ground using sand. In the Dezeen-produced video above, van Bon uses the bot to display the works of the Dutch poet Merel Morre on the streets of Eindhoven. “When you’re writing one [line of] text, another one is going away because people start walking through it,” van Bon says in the video. “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.” Combine it with an algorithmic poetry generator like Pentametron and I’ll be really impressed.
