It always rains the day you're moving or gets really icy when you have a lot of driving ahead of you. Murphy's Law definitely applies. If you could control the weather things would be much easier, and Design I/O wants you to feel like you can. Their installation allows participants to make it rain, produce wind, drive snow and bust out of ice blocks, all with a wave of your arm.

The exhibit uses multiple HD CCTV cameras and a Blackmagic UltraStudio Mini to track users' heads, hands and feet and react to their gestures. These data work with special green screening effects created through openFrameworks to enable lightening bolt wielding and tornado conjuring. If you've ever wondered how good a Poseidon you would be, this is the way to check. [Creative Applications]
