Let Q be a compact reflection orbifold of dimension at least three. By using Klein's model for hyperbolic geometry, hyperbolic structures on orbifolds provide examples of real projective structures. If Q admits a hyperbolic structure, then such a hyperbolic structure is unique. However, the induced real projective structure on some such orbifolds deforms into a family of real projective structures that are not induced from hyperbolic structures. We will describe a large class of compact hyperbolic reflection orbifolds with such deformations.
