Thanks to forums user Firlefanz for sending this in – it’s wonderful!
I built a night light for my daughter in the shape of a flower made by wood from an old apple tree. A Trinket Pro is inserted in the base. In the top sits a 12x Neopixel ring. The colors can be changed via IR remote.

Adafruit Pro Trinket – 5V 16MHz: Trinket’s got a big sister in town – the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Read more.
NeoPixel Ring – 12 x 5050 RGB LED with Integrated Drivers: Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5″ (37mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.
