Hello, 
I would like to present you Breathing Games, a commons to foster self and mutual care in respiratory health.
In the last months, we have been working on a flow-based, 3d-printed controller to play games and test one’s lung capacity. The goal for September is to enhance the device and its documentation, and prepare for mass production… but maybe you have ideas on how to improve our work, adding environment sensors, …? 
Feel free to share your ideas and contact us!
