Hey Tadd, If you’re talking 10 years ago time frame I’m guessing you’re referring to the AmbientOrb. It was a device from an MIT group/project that signaled the state of the weather, stock markets, etc... Here’s an article about that device.
http://www.nbcnews.com/id/4758931/ns/technology_and_science-tech_and_gadgets/t/new-technology-relies-human-visual-system/ There have been many of these types of devices launched as products/kickstarters/DIY projects since then, in various incarnations. I’m sure you can find examples on Hackster.io. Here’s one I built: https://www.hackster.io/breakpointer/ambient-web-connected-color-orb-91b9fd Also, here’s a more complete Rpi based tutorial: https://www.raspberrypi.org/magpi/cheerlights-orb-a-node-red-tutorial/ The neopixel from Adafruit is great for this type of thing. https://learn.adafruit.com/neopixels-on-raspberry-pi/overview Hope this helps. Cheers!
