One of the fun projects that I TD’d for Spinifex was the Lexus hoverboard engagement. This engagement used a Wii balance board, midi controlled fans, cameras, audio, 18 HD displays and 10 PCs to drive the experience. I selected all of the hardware and oversaw the technical integration and deployment of this fun experience. I used to work with cave environments in the past, and can still say that I believe they are more immersive than most HMD based experiences if done well. The only problem here was that people often fell over when the skateboard started moving!
The activation was a huge success, with a great auto generated branded take home video for participants to share with friends. If we had more room, a rear projected surface may have been preferable due to the monitor bezels.
And here is me riding the slide!
