Drawing on canvas usually remains flat, but a 3D pen allows you to bring certain details out beyond the surface. Plastic lines can be layered, turned into relief, and connected to the finished image. Participants will learn how to use this tool to create an expressive painting. The session will start with mastering the 3D pen. Participants will try to carefully draw a line and form small three-dimensional elements. Then flowers will appear on the canvas, as if growing above the background, and the walls of the drawn castle will gain noticeable texture. Everyone will be able to come up with their own plot and decide where to keep the flat drawing and where to add protruding fragments. Mistakes here become part of the experiment: the material allows for searching for form directly during the work. The masterclass will be conducted by Alexander Sevryugin, an employee of the "MediaLAB" hall. The number of places is limited, so registration must be done in advance via email at medialab@rgub.ru. The email should specify the name and date of the masterclass, the participant's name, and phone number. Where to go in Moscow is known by KudaGo.
