#2This mask craze is confusing to me. Not surprising, just confusing.

It's Mardi Gras lol

I could be wrong, but I've always thought this was connected to Burning Man (masks are functional there).

Are you referring to the cloth surgical-style face masks, or masks at raves?

#7Fun! It's amazing how ubiquitous WS2812Bs have become in such a short time. They're wonderful for everything from wearables to signage to room lighting, and there are 12V versions available if you want to drive longer strings.
Some advice for people seeing this article in 2020: you might consider using a more modern microcontroller which supports DMA for new projects today. The ATMega328p which is used in Arduino Unos and Nanos is a reliable workhorse, but it's also slow and expensive compared to modern 32-bit MCUs.
Check out ESP8266/ESP32 or ARM Cortex-M cores. They're fast enough to make buttery-smooth animations, they have enough memory for thousands of LEDs, and DMA lets you set up a continuous data transfer to the LEDs which does not require CPU time. These days, there are plenty of ARM Cortex-M boards which work with the Arduino IDE while still being a hair cheaper than "Arduino" knock-offs, and ESP8266 boards let you control your patterns over WiFi.
If you're starting to learn about embedded development today, it's not a bad idea to start with more modern hardware; projects like MicroPython and Arduino support a wide variety of chips.
Also, if you use the Arduino IDE and appreciate their work, consider buying a genuine Arduino Nano. They cost a bit more than $3-5:

#8This is cool project, the effects look great! makes me think of 'Ruiner' computer game, the main character had an animated mask set in a cyberpunk world.
Great work enjoyed the article :)

Im building a setup now. Any tips on libraries for esp8266 to control the maximum number of leds via i2s DMA?

Thank you for this post! When I started, I didn't realize how low powered these nanos are. I spent forever getting the variables under 1.1kb but I just discovered the teensy 4.0 that supports 1000x as much memory and 30x the processor speed.
I am still glad I started with the nano because it got me to refactor my code and make it memory efficient.
