 You can print your own UFO. All you need to do is order an Adafruit Huzzah, some wires, and print the UFO in black and transparent filament. The Huzzahs ESP8266 hosts wifi and a web server so that REST calls plus a simple hybrid web app are used to configure and control the device.

 Cut off one end of the USB cable and use the 5V line (red) and ground (black) wire for powering the LED strips as well as the Huzzah ESP8266 microcontroller. Make sure to isolate the other wires to make sure you don't damage the USB source or get in contact with the other electronics.

 The Huzzah ESP8266 microcontroller is mounted on top of the downlight inlay and also keeps the 2 short LED strips in their position. For proper isolation, put the printed platform with the 4 pins upside under the Huzzah board and then put all of it inside the clip that holds everything in place.
