Ask HN: Have you ever been part of a remote hackathon?

At work we're thinking of holding a remote hackathon to help with morale now that everyone's working from home. My main questions are 1) what (if any) video conferencing tool did you use? I'd be especially interested in how the team presentation aspect at the end worked, and 2) what was the experience like? Would you do it again? Thank you everyone for your time!
