Motors Turning computer chair around with a motor?

Can you give us a hint? I'm really struggling to think why anyone would want this

 

I'd also like to modify a chair but so it tips backward when I press a button mounted to my desk. Preferably the same signal could trigger a trapdoor behind the chair. Any ideas? Also if it could be light enough to mount in a Zeppelin that would be good too.

 

Give Graham Norton a shout.

 

Is that a euphemism?

 

No, but he has a chair that fits the bill.

 

I have an old bike helmet stored away for a elf n safety test however it’s going to be some time before we get to the prototype due to funds and research.

So I've been speaking to some robotic guys and apparently a simple button + solenoid would do the trick however connecting this to the computer and getting it to work brings even more problems. I’m thinking the solution would be to use a ready built robot using Arduino and just programming it in!
