As described each carriage 30 comprises an elongate body (34), Fig.3 (not shown) adapted to be secured to a strip 20, and a pair of wheels (28) at each end of the body (34). The ends of the bodies (34) are in abutment with adjacent carriage bodies so that all strips are displaced by the same amount, and adjacent carriages may be interconnected by easily stretched elastic bands. Return of the  strips after displacement may be assisted by light springs. Carriages may be used byP. T. F. E. or ball races the guide may operate P. T. F.

When installed in a theatrical stage the upper support 40 may serve as part of another piece of equipment (e. g. a screen) and the lower track may be recessed or provided with ramps to protect it when the large object moves over it. The screen may be coated for displaying projected images or may be ornamented and serve as a background. In a preferred use a large object (e. g. vehicle, boat or large animal) has its image projected on the screen and the real object may then be introduced through the screen so as to appear to have emerged from its image.
