Karkhana conducted Creative Computing workshop for a group of artists and engineers. It was designed to create interactive projects for Yantra 4.0. Yantra is an annual art-science-tech showcase that brings artists, engineers, educator and researchers to the same platform and creates collaborative working environment among them. The workshop for art-tech collaboration ended with a twitter activity where everyone wrote their feelings about the Creative Computing session. Most engineers were excited to see the process of generating project ideas and the uniqueness of those ideas that evolved throughout the session. Artists, after visualizing the possibilities of technological intervention were excited to implement it in their regular work. Yantra organizers decided to take four projects from the workshop for the annual showcase. This blog is about those four ideas, their evolution, successes, failures and learnings in our three month long journey from Creative Computing workshop to the Yantra 4.0 showcase.
