Flower is based on a ESP01 module programmed via USB, and controlled via Wifi. It have one button for control and five RGB LEDs that can display any number of animated visual signals.

I designed the control system to be housed in a thumb-stick-like enclosure, or optionally using an extension.

For the interactive part I designed a cute PCB with only 11mm in diameter:

In the other side, it have pin connections for a cable and a push button.

The idea is to have it enclosed in a flexible silicon-like material (maybe hot glue for a first prototype)
