I love watching long lines of cascading dominos and Rube Goldberg type machines. Solve Media sent me their "All Humans, Happy Holidays" video with a great Rube Goldberg-like contraption that uses many inventive ways of triggering the next event.

It's the brainchild of Ari Jacoby, CEO of Solve Media. It's a lot greener than posting out thousands of holiday cards but it took a lot of work: 900 hours of planning, involving a team of 12 over a four month period.

Engineering led by Matt MacMillan, UPenn Engineering alumni; Creative Direction by Machele Nettles of MacNet Design; Videographer was Lendl Tellington.

Solve Media runs an advertising network that monetizes CAPTCHAs with display or video ads, a creative business model reflected in the creativity of the video.
