CV Dazzle 

Earlier this year, writer Robinson Meyer spent some time wearing face paint known as “CV dazzle” in public, in an effort to conceal himself from the current surveillance state.

It’s clear that this is not a real solution to prevent tracking. However, as a performance piece and a commentary, it’s very interesting.
