I was planning a game in the class party of my son – the children should guess, what pictures are showing, though they see only a part of that picture.
I found only one program – and this was not free. Therefore I wrote a program in VASmalltalk to give me the base functionality: MSKClick.
Just put all pictures into a directory. Then via “Load List” select this directory and the program loads all pictures. Then the rest is controllable via function keys:
F5: load next picture
F6: toggle auto showing
F7: show next part of active picture
F8: shows the picture at once
F9: animate (auto opening) to the end until the whole picture is viewable
This short video shows, how it should work
