Just a "small" (well, 90 cm diameter ^^) project with WS2812 stripes (60LEDs/m), arduino and some lasercut materials. It consists of a baseplate out of finn cardboard, with flower-formed channels where the LED stripes are hidden, above mirror plate with insterted difusse acrylic. After some distance holder rings (made out of cardboard again) the top spy mirror plate follows. The sides are afterwards covered with a real stone verneer (Slatelite) for nicer look. Arduino & power supply at the back for testing (with the ColorPalette demo running from the FastLED library). Next steps: mapping of the pixels and doing real animations.
Building was actually less complex than it might look like, just stack a bunch of lasercut pieces of cartoon, mirror/spy-mirror/diffuse acrylic, with a bunch of WS2812 strips behind and finally some Slatelite stone verneer for decoration - Short building instruction can be found here. The fun part with mapping starts is still going on.
I just showed my significant other the video, and she was slightly impressed, as it's hard to make out the scale of it from the video. Then I showed her it was a coffee table and she said, "want! want! want!".
