“Lacer/actions” is my research-project about the reality around us. I have shot and archived over 150,000 photographic images on decomposed and torn paper of advertising posters, natural cracks, urban and industrial materials. I think it’s a world of colors within the colors of the world. Because we can see things that we do not even imagine. Yes, didactics of perception, increasingly necessary in cognitive (and non-cognitive) skills. It is the most colorful, funniest, democratic and inclusive teaching method. So, jump into it!
