Daisy is a robotic arm several times taller than a human, and it's got a massive fiberglass cargo ship propeller attached to it, which it'll randomly wave about in the air (slowly, luckily). It also has cameras fixed to its stand so that it can detect the presence of onlookers, and track them withits giant flower-like face.

Daisy is a robotic sculpture by designer Christian Moeller, and it currently sits in Terminal 3 of the Changi Airport in Singapore. Moeller has a video of the sculpture in action over on his site.
