Pressing buttons cycles through preprogrammed colours and animations.
I had a spare IKEA LACK side table laying around after moving in with the lady.
Selling it sounded boring, so I came up with the idea of turning it into an infinity table.
Infinity tables use LEDs and mirrors to create an infinite tunnel effect.
Manual Labour
I cut a hole in the table, attached WS2812 LED strips along the edges, and ordered a mirror and two-way mirror online.
For the electronics I made my own PCB with an ATtiny85 for the logic, mini USB for power, and buttons to alter the appearance.
