The idea was not mine but copied from an Instructable by Chris Parker and all accolades go to him for all his hard work – thanks! Instructables link.

On my wish-list for 2020 is this wall panel consisting of WS2812B LED pixel strips controlled by an Arduino Mega.  Each tile has a bush button under it enabling the user to interact with it.  The Instructable details 3D printed tiles but I think using 2mm translucent acrylic sheet with 3D printed frames will save a huge amount of print time.

This will be a great platform for fun and Arduino coding…watch this space!
