What did you make?

I built an interactive Jujutsu Kaisen-inspired web experience that uses MediaPipe hand tracking and Three.js particle effects. Different hand gestures activate different cursed techniques, such as Red, Infinite Void, Hollow Purple, and Malevolent Shrine, each with its own unique visual effects.

What was challenging?

The biggest challenge was combining real-time hand tracking with 3D particle animations while keeping everything responsive and smooth. Tuning gesture detection and creating distinct particle effects for each technique also took a lot of experimentation.

What are you proud of?

I’m proud that I was able to create an immersive anime-inspired experience entirely in the browser. Seeing hand gestures trigger different cursed techniques in real time made the project feel interactive and rewarding to build.

What should people know so they can test your project?

Allow camera access when prompted, as the project uses your webcam to detect hand gestures. Hold your hand clearly in front of the camera and try different finger positions to activate the various cursed techniques.
