Some odd LED based product offerings Infinity Mirror Dress offered for $1800 on Etsy LED Nightclub Eye Lashes $6.99  @ Amazon  Motion sensor in controler worn on head effects lights. Hair Growth Hat with 272 Lazer Diodes -  $2,999 capilluspro (There are cheaper models with fewer lazers for the less "faithful") Persistence of vision displays Cleverly engineered, this technique makes the most of a relatively small number of LEDs, most commonly seen in sl called "Holographic LED Projectors" that show floating sneakers in malls and "Poy Sticks" spun on a rope by artists to make pretty patterns in place of the original flame pot. A fun concept, imagine an alternate universe where engineering innovation stopped before developing raster scan or LCD style displays, where they may still be watching electro-mechanical TVs, like this 1928 toy for the wealthy using a slotted spinning disk. .
