I think this is called friendship lamps or touch lamps. They're connected online and when one person touches their lamp the other person's lamp lights up or changes in some way. There are a few Arduino/ESP projects for making these, or you can buy them. They're promoted as a way to keep a long distance relationship going.

I'm curious, what's the supposed effect?

I read and agree with the other comment here, but it's mainly a kind of nonverbal communication. I linked our computers and gave my gf the ability to change my background whenever she wanted, wherever she was, and vice versa. it's just a way of being close and all up in each other's business when we can't get all up in each other's business.
