Finally, the show over, the lad's proud parents are assured by departing
                         guests that their budding showman has a brilliant future.

                         In today's high-tech society a few seconds of barely discernible animation
                         flickering  on  a  suspended  bed  sheet  would  hardly  be  considered  an
                         evening's entertainment. However, for many of us, born in the pre-TV era
                         this was our first experience of movies at home.
                         Proof that there was a time when such simple diversions were popular is
                         evidenced by the hardware and software that still survives.

                         A wide variety of these toy projectors have been produced over the years.
                         They came in numerous sizes, shapes and colours even though, for the
                         most  part,  sharing  basic  operating  principles.  Most  turn-of-the-century
                         examples were, like many other tin toys of the period, of German origin.
                         Made  of  'Russian  Iron'  by  the  Nuremberg  firm  Bing,  they  spread
                         throughout  the  world  under  a  variety  of  aliases.  The  light  source  was
                         usually a small kerosene lamp complete with chimney. Optics consisted
                         of an elementary condenser lens behind the film gate and a single meniscus
                         projecting lens, fitted in a sliding barrel for focusing.

                         These were basic requirements for both still (magic lantern) and movie
                         (cinematograph) projectors. Additional mechanics necessary for movie
                         versions consisted of the hand cranked intermittent movement, usually
                         toothed wheel driven by a crude 'Maltese cross'. An alternative was an
                         even  more  fundamental  'beater'  movement;  a  rotating  bent  rod,  which
                         literally bashed the film through a frame (or so) at a time.

                         Geared to the intermittent movement was a rotary fan type shutter (usually
                         single  bladed).  Cheaper  versions  dispensed  with  this  technical  nicety
                         thereby  increasing  the  marginal  light  output  at  the  expense  of  severe
                         'ghosting' (vertical smearing of highlights). A guide was provided for the
                         film loop consisting of a vertical rod with a top right-angle bend over which
                         the film would travel.
                         Film subjects were usually simple line-drawn animations in either black
                         and white or lithographic colour. As explained earlier, the brevity of scenes
                         was overcome by joining the ends to form a continuous loop.
                         Longer films, of 30 feet or more, were also available, but all examples I
                         have seen thus far consist of discarded lengths of commercial feature film.
                         Toyshops sold these rolls in appropriately sized cans for a few pennies
                         each. Being inflammable nitrate based film, most of these ended up as
                         'stink bombs' at the hands of schoolboys whose interests lay less with film
                         techniques than pyrotechnics. What remains has usually gone the way of
                         most nitrate silent film, shrunken and decomposed. The shorter acetate
                         loops  have  usually  become  too  brittle  to  stand  projection  without
                         disintegrating.
