Electroluminescent Shirt
David Gill’s Total Dick Head site has this news which, frankly, ticks all the boxes:

“Alejandro Zamudio and a ‘team of designers and fans of Philip K Dick,’ have developed an ‘electroluminescent shirt inspired by The Man in the High Castle.’”
Zamudio writes:
“Recently we have created a prototype of an electroluminescent shirt inspired by The Man in the High Castle, by which dwellers of 1960s San Francisco can cast hexagrams from the Book of Changes and publicly display what the Oracle has said to them.”
The group’s website reads:
“The shirt itself is a very simple device that allows the 1960s dystopian inhabitant to obtain a hexagram that can be looked up in the Book of Changes. It also works as an active agent of randomness by publicly displaying the hexagram, thus giving onlookers an unsolicited random answer to a question that possibly hasn’t been asked yet.”

Brilliant.
