If the weather is getting you down, why not do something about it? The Augmented Reality Weather System from Magic Vision Lab can make you feel like you are standing in the middle of a downpour (complete with lightning), snowstorm or hail deluge. The helmet even simulates the hail stones bouncing once they hit the ground.
The simulator works by tracking your surroundings and then overlaying weather effects on top of the real-time video feed. Interestingly enough, there is no way to turn a rainy day into a sunny one. There is a lot of room for expansion on this idea, including a system to make you actually feel the virtual rain – come on, future!
