👍🏻 🚢 🚴🏻 NeoPixel + ESP8266 + PLYWOOD = WALL LAMP "BATMAN" (part 3) 👩‍👧‍👧 👨🏻‍🏫 🤦🏿

Nominee for the award "BOMZH-PROJECT 2020"
In this part, the monumental construction of this masterpiece will finally be completed! For those who missed - here are the first and second parts of this trilogy.
Rather, under the cut, there are a lot of pictures (and even vidosics)!

Well, a small video of one of the effects:
PSSSS You can also find the code for this device here: GitHub . What if it comes in handy ?!
That's the end of the fairy tale. Thanks for attention!
Then I take my leave. Your A.S.
