remotely adjustable rear spoiler?

hello every body.

this is my first post on this site so please bare with me if it dont make sence.

oh and i am in England so i apollogise for any slang or references that dont make sence.

here's the deal.... i have a v w golf mk2 gti and would like to fit a new rear spoiler to the top of the boot.

i would like to be able to adjust this spoiler so that it flicks up from a horizontal position ( so it looks a bit like a lancia delta rally car rear spoiler). i would like to be able to adjust this from in side the car with some sort of control on the dash so that i can set the pitch of the spoiler to what ever setting i wish.

because this spoiler will be some times fliked up whilst driving it wil need a system that meeens the spoiler wont move.

i was thinking of using electric window cables and motors but i am not sure of how to control this.

so theres the idea, i hope it makes sense and i look forward to your replys.

i thank you in advance for all help given.

cheers

cheers for the ideas people.

If iam honest i only want to be able to adjust the spoiler for looks. It might make a difference in cleening the rear window in the rain if its tilted right but i mean who actualy buys a car with an adustable spoiler if you cant play with it and make it stick up when you are cruising through town. I know some of the porsche 911's had an overide sh*tch for just such an ocassion. after all who cares what you spoiler is doing if you need to travel 95mph to make it operate. at 95mph you should be far more interested at what coming towards you!
