I spent some time looking into forced perspective drawings. I was trying to generate an effect where it looked as though a flat sheet of material was sloping downwards. There are plugins for inkscape that generate a perspective effect so the first step was to create some footplate artwork in a vector format (raster formats would also work in other programs like gimp). The original flat sheet was then warped to the second sloped sheet. I clearly should have made the second sheet shorter because the panels closest to the eye were actually stretched in length but the effect is still pretty prominent.
