I imagine about that the pattern can be communication tool in familiar object in our near life. So, I will project to block or building regular pattern for making sound & visual with tracing the pattern. The projected something (circle or whatever) reacts by people's acting and people can feel equally.
The block or building pattern
This is some prototype making function for making sound and visual with pattern. I think that the regular pattern will be impressed more than complex one. It can function with line hit or collision between moving circle. I will experiment variety expression and function structure more.
Patch
Line hit reaction
