Check out this video that demonstrates the Fanimation Air Shadow ceiling fan. This thing is basically a Transformer for your ceiling. The blades stay retracted until it gets up to speed, then they spread out. I just can’t think of a good Transformer name for it. Spin-imus Prime? Arm-itron?
It’s pretty cool as far as ceiling fans go. I love the way it swings its arms out as if to say it’s alive.
