is it possible to make a mirror application in android

Hey is this possible to make an application which can be used t开发者_运维知识库o see the image of our own like we did in the mirror ie the application should be act like a hand held mirror dont want to use the camera but want to make screen Act as mirror

It is easily possible by placing a small periscope on the back camera

If the device has a front-facing camera, just turn on the camera.

This is virtually impossible because the image displayed would depend on the angle of the screen.
