H.A. Ray wrote "The Stars" around 50 years ago--simplifying how star constellations can be viewed and envisioned. Compared to other astronomy books--Ray's book was easy to understand and an intuitive method of star gazing.

Today, LEDs can be used to convey information, and we can either use a mesh network of a bunch of LEDs into a matrix and display alpha numeric characters or entire words or we can used a system that uses fewer and more meaningful LED beacons. From a manufacturing stand point--a mesh of LEDs could be time consuming or expensive to produce. If we can figure out a method like H.A. Ray and come up with an early "Palm Pilot Graffti" way of conveying/signaling information we can produce more IoT devices with fewer LEDs.
