DoublePi

2π is the true constant of a circle and the inspiration for creating the DoublePi community where our core mission is to help build a more circular society. 
 DoublePi creates an easy and secure space where users can connect and share free, used/unused goods.
Users showcase eco-friendly DYI projects and engage in contests based on those projects. 
(2PI)Feed features ideas about living the earth-friendly DoublePi lifestyle.
