Seen last week in Geneva, next to temporary constructions for immigrants. What can we see here in this interesting "point of contact" - almost all have the same orientation (= same channels? same cultural group of viewer?) - they are grounded, do not at their regular position on the roof (= left here in a a hurry? not possible to climb to the roof) - they are very close to the sidewalk where people pass by (low number of people passing here anyway)
