Beyond Photography -- The Digital Darkroom by Gerard J. Holzmann, was
published by Prentice Hall in 1988.  It is a great little book and is
described briefly at http://cm.bell-labs.com/cm/cs/who/gerard/popi.html

I have dashed together a minimal framework for doing manipulation of an
image that is somewhat similar to what is done in POPI.  The attached
file-in works and is quite fun to play around with, though the user
interface needs a bit of work and it could be a bit faster.

Instructions:
(1) File it in.
(2) From the New Morph... menu, under Demo... create a POPIMorph
(3) Open a nice JPEG or GIF file
(4) Drop the picture onto the POPIMorph
(5) Change the return value of POPIMorph>>newAt: to change the
transformation function.  This is the place that controls what the
result looks like.

Not done, but great additions would be to have a place to type an
expression in POPIMorph as well as the ability to use more than one
source image.  Better yet would be to use scripting tiles to build the
transformation expressions.   Also fun would be to connect it with
the video capture work that various people are doing.

Have fun.  Any feedback gratefully received.

Mike

p.s. NB: This is an experiment only and shouldn't be considered for
inclusion in the main system
