Meet Pins Collective: a digital pin with a round screen that lets you better express yourself. It lets you wear the work of your favorite artist on your chest. These digital pins are compatible with iOS and Android devices. You can create your own design or use the work others have shared. The companion app lets you write any text, use background patterns, and change colors to come up with your own designs.
The developers are planning to release a SDK for Pins Collective in the near future. You can support this project on Kickstarter.
