Dear Reader

Who  can  help us to find - both commercial and public  domain  -
graphics  and animation programs for the following  requirements,
NOT  ALL OF WHICH HAVE TO BE MET although we would be happy if  a
major portion would?

We  would like to create some 100 to 200 signs and to  also  cre-
ate,  or obtain ready-made,  numbers,  mathematical symbols and -
possibly  even  non-Latin  - alphabets (all of  which  signs  and
characters being referred to below as symbols) for processing  on
our IRIS 31/30 in the following ways:

having the symbols write themselves on the screen as if they were
written by an invisible pen (or brush for that  matter);  linking
the individual symbols to individual keys,  so that striking them
triggers  the  "auto"writing  process which  itself  would  occur
pursuant  to  set  characteristics  (like  shape,  shadow,  size,
colour, surface structure, etc.);

modeling  the symbols (and having them write themselves) in  dif-
ferent  ways (2 or 3D),  giving them different  shapes,  colours,
lighting and surface structures;

increasing and reducing the size of the symbols; changing - espe-
cially slowly - their form,  surface structure, lighting, colour,
brightness,   the  angle  from which they are looked at  or  from
which light is cast upon them;  having them move,  or turn around
different axes or - which is important - fade away;  having other
symbols gradually appear instead of fading symbols; all by way of
animation;

said  manipulations occurring one by one or cumulatively to  one,
or  simultaneously to more than one,  symbol of those  displayed,
and even to several symbols scattered among - even many -  others
that are not modified at the same time;

as  the display is zooming in to the close-ups,  the symbols  not
focussed being be made to be pushed over the  screen  edges;

everything occurring at variable speed and being reversible;

onscreen  interactive  animation  data  change  facilities  being
welcome;

transparency not required;

programs  being comfortable,  requiring no or little  programming
themselves,  relying  on the mouse as much  as  possible,  making
economic use of stores.
