F21 Thread Screen – This is super cool. Be sure to watch the “behind the scenes” video so you can see how it works. It took me a while to work out that each “spool” is actually one end of a long rotor belt of “threaded fabric” that turns so the correct colour displays. You can send your own Instagram photo by tagging it with #F21ThreadScreen. (I sent mine this morning but it hasn’t shown up yet. Not sure how long a backlog they’ve got!)
