File:LS+mirror.png

Summary
I took the public domain image of the Last Supper and used GIMP to create a mirror image, copy the original and the mirror to two layers of a new image, superimposed them by altering their opacity and then exported the resulting image as a PNG.

This should more-or-less recreate the image that Slavisa Pesci made.

I adjusted the image to line the two Jesuses up with each other, as in Pesci's image. - Troy34
