Cypher V is the College of William and Mary's annual hackathon. It's an opportunity for students to come together for a weekend and learn new stuff, create cool projects, and win prizes. This year, our goal is to make the event more accessible and welcoming to everyone, regardless of their skill or experience levels. We hope that Cypher V will be a place for people to innovate and develop things that they had never considered before, so please join us in making this goal a reality!


All college students (undergraduate and graduate) or recent graduates (within 12 months of the event) are eligible to participate!


Please submit the source code for your project, as well as a description of your work and any presentations you created.
