Good point - I should have probably shown the direct interaction too (touching the actual fabric in space) - there's a gif here: https://jmp.sh/s/lHqJm6NEvqMqkXMPyUpZ. It was a little but laggy when also screen recording on device.
In the video I am looking at where I want to interact and then using a pinch gesture and the sounds are mapped to different cells of the cloth. By either looking and tapping, or playing directly you can hopefully play your intended sound.
