<Ul> <Li> slipping slides: a movable glass plate with one or more figures (or any part of a picture for which movement was desired) was slipped over a stationary one, directly by hand or with a small drawbar (see: Fig. 7 on the illustration by Petrus van Musschenbroek: a tightrope walker sliding across the rope). A common example showed a creature that could move the pupils in its eyes, as if it was looking in all directions . A long piece of glass could show a procession of figures, or a train with several wagons . Quite convincing illusions of moving waves on a seas or lake have also been achieved with this method . </Li> <Li> slipping slides with masking: black paint on portions of the moving plate would mask parts of the underlying image - with a black background - on the stationary glass . This made it possible to hide and then reveal the previous position of a part, for instance a limb, to suggest repetitious movement . The suggested movement would be rather jerky and usually operated quickly . Masking in slides was also often used to create change rather than movement (see: Fig. 6 on the illustration by Petrus van Musschenbroek: a man, his wig and his hat): for instance a person's head could be replaced with that of an animal . More gradual and natural movement was also possible; for instance to make a nose grow very long by slowly moving a masking glass . </Li> <Li> lever slides: the moving part was operated by a lever . These could show a more natural movement than slipping slides and were mostly used for repetitive movements, for instance a woodcutter raising and lowering his axe, or a girl on a swing . (see: Fig. 5 on the illustration by Petrus van Musschenbroek: a drinking man raising and lowering his glass + Fig. 8: a lady curtsying) </Li> <Li> pulley slides: a pulley rotates the moving part and could for instance be used to turn the sails on a windmill (see: fig. 4 on illustration by Van Musschenbroek) </Li> <Li> rack and pinion slides: turning the handle of a rackwork would rotate or lift the moving part and could for instance be used to turn the sails on a windmill or for having a hot air balloon take off and descend . A more complex astronomical rackwork slide showed the planets and their satellites orbiting around the sun . </Li> <Li> fantoccini slides: jointed figures set in motion by levers, thin rods, or cams and worm wheels . A popular version had a somersaulting monkey with arms attached to mechanism that made it tumble with dangling feet . Named after the Italian word for animated puppets, like marionettes or jumping jacks . Two different British patents for slides with moving jointed figures were granted in 1891 . </Li> <Li> a snow effect slide can add snow to another slide (preferably of a winter scene) by moving a flexible loop of material pierced with tiny holes in front of one of the lenses of a double or triple lantern . </Li> </Ul> <Li> slipping slides: a movable glass plate with one or more figures (or any part of a picture for which movement was desired) was slipped over a stationary one, directly by hand or with a small drawbar (see: Fig. 7 on the illustration by Petrus van Musschenbroek: a tightrope walker sliding across the rope).
