The Thought Project by Simon Hogsberg is really an awesome piece of work:
Over a period of 3 months I stopped 150 strangers on the street and asked them what they were thinking about the second before I stopped them……55 of the 150 thoughts are presented on this website as quotes.
I know I’ve often wondered what other people are thinking about when I walk by them on the street or sitting down somewhere. The answer is complete randomness, and it’s wonderful.
Careful, the site is addictive.
