The main problem actually will be that the UV needs to be stretched from the center out. So you will most likely need Fredborgs code archive entry for PickedU PickedV to get the "picking point" UV and stretch it from there.
Your projection has a different problem anyway: you only do one pic ... that can not work unless you are prependicular to the wall and the wall is flat ...
btw: Did you have a look at Fredborgs image projector sources he uploaded long ago? (the batman like projector in a closed room)
