My last-minute submission.
This is my entry for the Config Makeathon.
I built a 3D brick simulator where you can create and play with LEGO-style bricks using only your hand gestures.
Instead of clicking through menus, you can point, pinch, rotate, and move your hands to build in 3D space. You can choose different brick types, change colors, rotate pieces, and experiment freely.
Hand gesture input for a brick builder is the right idea for this kind of spatial interaction. The pinch-to-place mechanic maps well to how people actually think about building with physical pieces.
Thank you. You're spot on about spatial interaction because that's is the idea, because I think we're moving towards spatial interface and experience so I created something that reduce the use of mouse/keyboard.
