Teams
Teams of 1–5 members. Solo participation is allowed. Find or form a team on the Teams tab.

Projects must be built during the hacking period and submitted before the deadline. Include a working demo or repository link. Public libraries and APIs are fine, but the core of your project must be original work created at this event. One submission per team.
