Funny graphical programs with Allegro

This is a very slow ongoing project to convert all the programs in "Graphical DOS mix" ("ssdosmix",
see below) to 32-bit programs for Windows and Linux using Allegro. The programs can be run in console
(DOS) mode or in a window. The programs were compiled using Allegro game programming library
for graphics and sound and Microsoft Visual C/C++ 6.0 compiler. The Linux version was compiled
using GNU gcc C-compiler. Don't forget to read the readme file before using the programs.

At present the package includes the programs "lworm", "cube", "transf" and the improved elastic
pendulum program "elpend" and the new chaotic pendulum program "chaopend". New programs
are only included in this package (not "ssdosmix").

New! The main difference between ssfun2 and the old ssfun package is that the program "chaopend2"
is improved and can run several chaotic pendulums at the same time. All programs are now terminated
by pressing the key "q" (quit) only. The program "lworm" seems to work now, but is slow in Linux.
Use the old version (ssfun) if you have problems. Don't forget to read the new readme file as usual.

New, January 2 2021. The binaries in ssfun2.zip are now recompiled using allegro-4.4.2-msvc-10.0.zip
with Microsoft Visual Studio 2019. This gives better and more secure executable files that work well
also with Windows 10.

Graphical DOS mix

This package contains 28 funny graphical C-programs for DOS under Windows 98/2000/XP and plain
DOS on older computers. The programs are compiled using the old 16-bit Turbo C/C++ 2.0 compiler.
Some of the programs have moving graphics. Programs to make random dot stereogram images and some
fractal images are also available here. Don't forget to read the readme file before using the programs.

Note. These programs do not work with 64-bit operating systems (only 32-bit).
