yep, thats a pretty good idea of what I'm on about, I'm a bit concerned about
1/ Small compressor, no air reciever - that size of compressor is fine for spraying paint etc... but to move a person through a whole race, I can see the pressure dropping quite a bit, movements would slow...
2/ Cylinders would need to be the 'cushioned' type - this means you don't get a sudden stop at the end of stroke, either through a rubber stop or through air being fed back in, adjustable....
3/ The monitor being 'thrown' about!!! I wonder how long a monitor/TV would last under extreme forces????
4/ Noise, that picture shows the compressor about 3 feet away! Really you would want it in a different room, you would need a reciever then (acts like a battery, stores the compressed air) to take up line loss etc....
Werner, yes stepper motors/servos are the best option, quiet and very, very, reliable

I wish I had access to cheap/free servos! I used to program factory automation, one compay I worked for made garage doors and the production line had approx. 750 servo motors, shame I don't work there now
The electronic side shouldn't be a problem, if you can get the forcefeedback signals, I presume they will be analogue anyway or perhaps different levels as the force changes...
I would certainly consider fitting a large bass shaker underneath anyway to get the full effect.
Would you move the TV as well? I suppose you need to but I really don't know about the lifespan under those conditions...
