This project was developed for the Spanish TV show El Hormiguero's 3.0 debut with singer Alejandro Sanz. It consists of a SCARA robotic arm controlled from an Android tablet that pours oil-based paint over water to then colour 3d printed objects by dipping them with a linear actuator. It was a robotic take on the popular swirl painting technique.

The mechanical design was created by Javier Isabel, the aesthetic design by Alberto Arribas and the mask by Sonia Verdú while I took care of the programming.
