The Floor Is Lava (2015) by Maarten Lodewijk and Maarten van Hees caught my attention because it remined me of the Wii balance board I used to play with.
The project is a virtual reality installation in which the participants tries to keep balanced while crossing over a lava lake. They even incorporated wind to disrupt your balance.
Thinking further, I foresee how this project can be developed and become really cool game material. Moreover, this combination between balance and VR could in the future be used for training purposes of for example skiing, cycling, surfing, etc. Not only will this enable people to keep exercising whole year, it also allows people to stay at home: no pollution by traveling!
I think it is time to bring the world to our living room, instead of everyone travelling to see the world. I like how this project tries to build a foundation for this utopia.
