45' 45' ...nooo

The mirror system isn't working out, well it is, but not how i want it.
If i put the projector in the base, and project through the 'horn' of the gramophone,
then the horn has to be massive, to make sure the image stays in tack.

sooo new plan is to find a mini projector and place it within the opening of the horn,
so i can then do two 45 degree angles, to project it on to the wall in my installation.

Any one know where i can find a mini projector ? ... hope fully with good spec's
since i cant really start making my gramophone till I know the size etc of it.

or even have any idea's on different ways i can go about this ??
