Hydra
Hydra is an open-source creative coding framework for live-coding visuals directly in the browser, created by artist and programmer Olivia Jack. It lets users generate and manipulate real-time graphics using a simple JavaScript-based syntax, making it popular for VJing, performances, and experimental visual art. Hydra emphasizes improvisation and collaboration, allowing multiple people to connect and code visuals together over the internet.
