In 2017, he created the "Carpet of Joy" – an artwork to protest the excessive littering in Goa, on the 100th anniversary of Gandhi’s first experiment of "satyagraha" (which Gandhi began in Champaran on April 10, 1917). It used 1,50,000 discarded plastic bottles, collected from beaches and hotels in Goa, to weave a carpet. To celebrate the anniversary, Kerkar also worked with a team of software engineers and Dmytro Dokunov, a digital artist from Ukraine, to create an augmented reality smartphone app called "Gandhi AR", which would display a bust of Gandhi when pointed at any Indian currency (which features Gandhi on it).
