Of course! Every day, we all have some kind of screen in front of us, smartphones, tablets, computers, etc.. So it is a good idea to place your sigil on some of these screens. Even if you are not techy, it is easy to set up your screen saver or wallpaper to display your sigil. In addition, as far as I know, there are some computer applications that display your affirmations at high speed. The intention behind this is not to interfere in your work but to be perceived by the subconscious mind. In any case, do not hesitate to develop your magic by incorporating new technologies.
