We want you to spend 48 hours building hacks that help all of us reconnect with nature. The first ~12 hours of the event will be heavily workshop focused if you're just getting started. The remaining time will be packed with mini-events and hacking time!

Students can include high school students, university undergraduate or postgraduate students, and people who are in vocational training such as apprenticeships.
