Chromatrope lantern slide with circular blue and yellow kaleidoscope pattern.

Developed in the 1840s chromatropes are mechanical slides that create a similar effect to a kaleidoscope. An external handle attached to the slide connects to internal moving parts designed to rotate coloured or decorated glass discs. This then creates colourful patterns or scenes that move when lit from behind by a magic lantern. The patterns can then be enlarged and projected onto a wall.
