At the moment i'm trying to find a way to use planes to impact "pixels" into glowing, when any part of a plane touches one of these "pixels" it glows but so far i can't find any way to do that or if it's the most efficient way to go about this

i don't want to use UVs to animate the lights because that would take too long, i'd rather use planes or other objects to make the "pixels" glow

If there is any way with (free) addons (like animation nodes) please let me know

i'm using this to try to make a pixelated monitor face on a character i'm working on

please don't use the compositor
