Lights controlled by a helper/objects


I’m looking for a plugin that can control vray lights. I have an array of 100 x 100 lamps (imagine a grid of small led lamps) and I’m looking for a way to animate these lamps so that I can make patterns with the lights turning on and off. I’m thinking the easiest way would be if I could just animate some helpers and only the lights within these helpers were turned on, while the lamps outside the helpers were off. I have been looking for scripts and plugins to achieve this with without any success. Can any of you think of anything that could help me?
