Daniel de Bruin built a homemade thrill ride that looks a bit like if The Zipper merged with a camera jib on steroids. The video says the machine reacts to the rider's biometrics, but it doesn't really show how a rider's heart rate changes ride speed.
At any rate, it's still pretty cool and could be lots of fun with the right VR accompaniment.
