[PROJECTOR] Keystone correction on a ~90° angle

[streambinder]

Hey, guys.
It's my first question here, and probably I'm mistaking which section place this thread in (maybe you'll help me with that, too).

The matter is: do you know a projector able to make a Keystone Correction on a distorted projection caused by a ~90° angle between the wall and the projector itself?

If I'm not that clear, just tell me: I'll try to explain as good as possible.

Greetings.

Please explain in details and simple words...

Does a projector able to manage a projection - so to fix the distortion of the image - from a less than 3cm distance from the wall it projects to?

I have one questions, why use a projector if you just projector from just 3cms away ??? Generally projectors are not made to project from such a short distance, so I think keystone correction will not work well on projected images from projector places 3cms away, if it is 3 meters then for sure keystone correction works well and there are many projectors which have this facility.
