We went up the Semnoz this afternoon, taking our two-and-a-half year old baby on a no-pram-allowed walk for the first time. In addition to the usual suspects (cows and goats, mostly), we also ran into Benoit Pereira Da Silva, an application developer at the helm of a contraption he uses to code and walk at the same time. If I understood correctly, he has programmed the drone to document his walks.
