'Mooch' is a small experimental installation project done at 72by3 studio. 'Mooch' is built using open CV face detection and processing. A camera detects number of faces in front of it and adds mustache or "mooch" as we call it in Hindi, to each of the faces. First 'Mooch' prototype was installed for five days at Amdavad Ni Guffa, art gallery in Ahmedabad, India. 'Mooch" quickly became popular amongst children, elders and old people. A very quick, funny and engaging interaction made every one smile. Different gestures and expressions were captured through out five days of exhibition.
