Various clock-like devices to express time in public space

Why do I blog this? fascinating towards the diversity of clock-related devices to indicate time in public space. The first one is definitely my favorite as it's sort of absurd.

It's been a while that i collect such examples, I don't know what to do with them. Perhaps something will emerge out of this, a typology or sth else and I'd have to think about a design research workshop with students.
