"Light Up Someone's Holiday" is Improv Everywhere's latest mission and it's a heartwarming one.
...We created a custom-built set that allowed random New Yorkers to instantly deliver a card and light up someone’s holiday. Participants were surprised as Christmas lights lit up the plaza and their message was displayed on a 30-foot wide screen above.This project is a collaboration with Hallmark, who provided us with an assortment of Hallmark Signature Cards for the project.
See how they pulled off this stunt on their blog.
