One is referring to the placement of the projector itself, one is referring to the placement of the mirror that projects the image.

People tweeting stuff. We allow tweets from anyone.

RULES:

  1. Mark NSFW content.
  2. No doxxing people.
  3. Must be a pic of the tweet or similar. No direct links to the tweet.
  4. No international politcs
  5. Be excellent to each other.
  6. Provide an archived link to the tweet (or similar) being shown if it's a major celebrity, figure or any politician. If you replace the "x" at their site with xcancel (so it beomes xcancel.com), and you're not on mobile, it will save video. https://web.archive.org/save is another great option. Archive.is is no longer recommended because they remove/alter content.
