Joaquín was invited to give a lecture and a workshop that he called "VIDEO CROSS PROCESSING", a name inspired by the classic 90's C-41 chemical reversal process. During the workshop, 25 students shared an exciting experience playing with lo-fi-video-techniques, generating analogue glitches, textures, errors, colours, cathode distortions, graphic patterns and a wide range of artistic expressions achieved via analogue screens; from tube and flat TVs to mobiles phones.
