Wordwalk

In the same way people sometimes record soundwalks, consider the possibility of a wordwalk: transcribing any words you come across during a walk.

Consider also:

• Reinterpreting these words after the fact by inserting line breaks where desired
• The constraint of not stopping to write down words in dense areas
• (From Caitlin) write homophones of words, or semantically connected words instead of the words themselves (a "cockney wordwalk")
