bucket heads; machine of perception

Buckets were deviated from their normal use, to create hats that alter the users' vision and confuse them by the means of mirrors "Some allowed the user to see in one direction or not at all, causing hesitation. Even though everyone knew that nothing was out there, many still experienced difficulty walking in a normal fashion. Other buckets split or flipped the directions of sight, causing confusion and even nausea. People were either walking crooked, not realizing the distance walked, or confused about why the distant mountains had changed directions."
