One Piece birthday game

My husband loves One Piece, so I organized a themed party for his birthday and wanted a gift he could play through.

A pirate letter tells him that Luffy has sent him a Devil Fruit, which he has to open with his hands. The phone camera reads his gestures: he pinches and spreads two fingers to open the chest, makes four eating gestures to finish the fruit, and then shows a heart with his hands. Warm words for him appear on screen, followed by our photo.

I started in Figma Make, then moved to Cursor to finish the app and deploy it on Vercel.

Gesture recognition was the hardest part to get right, and the part that delighted him most.
