I've been trying to build an old-school robot avatar with bits that light up while the wearer is typing a message in chat, like the effect when the classic Robot in Lost in Space was talking. I've scoured the internet and I swear I can't find a good example of how to make this happen. I'd even buy such a script from the marketplace but either I haven't come up with the right key words or nobody sells it. Is there anyone here who can take pity on me?
