SuperMaze software is a simple to learn and play humorous non-violent hunt-and-shoot game using Smileys as the main actors in a maze style environment. You dont need more than the cursor keys and the space key to control your Smiley. The aim of the game is simple: Hunt each other and try to reach as first the win score.

There are several different mazes supplied with the game in various sizes and styles. SuperMaze is fully networked and multi platform and so playable on a vast amount of computers. Windows and Linux builds are already available. Needless to say that all platforms may play together in networked games.

The game does not require the very latest hardware. A moderate system with 800 Mhz is sufficient to play. See the Screenshots section for some visual impressions.

SuperMaze is freeware! Download your version of the game right now and play a round with up to 15 of your friends online or in a LAN.

libGLI is a multi-platform library for creating 3D user interfaces, based on OpenGL.
With the help of this library, programmers can add in their own graphical application elements for the user interface and connect interface objects to their own programs with callbacks.
In other words, GLI sits between the user and an OpenGL application.
Using libgli
libGLI is built first of all to relieve the programmers who build graphic applications based on OpenGL and dont want spend half of the time for programming their own user interface. In particular, libGLI will be useful for small and average projects, where the majority of time is spent not on the user interface, but on the REAL purpose of the program. But thats not to say that libGLI is intended for small projects only. libGLI has sufficient features for building both simple and complex interfaces.
The main feature of libGLI is that it is a general interface, i.e. programmers can create interface objects of various form, color, size, etc.
libGLI is a multiplatform library written in C++. All objects are based on classes defined in the library. The programmer can inherit from these classes to build new objects.
Enhancements:
- Updated Files: INSTALL README TODO ChangeLog
- New Files: COPYING man-pages
- New GLUT Demo: EditBox
- editbox: Added Function GetText

Prima is an extensible Perl toolkit for multi-platform GUI development. Platforms supported include Linux, Windows NT/9x/2K, OS/2 and UNIX/X11 workstations (FreeBSD, IRIX, SunOS, Solaris and others).

The toolkit contains a rich set of standard widgets and has emphasis on 2D image processing tasks. A Perl program using PRIMA looks and behaves identically on X, Win32 and OS/2 PM.

Prima project includes a visual builder and a graphic POD viewer.

Building:

A Unpack it somewhere. Use

$ tar xzf Prima.tar.gz

on systems with GNU tar, and

$ gzip -cd Prima.tar.gz | tar xf -

on other systems.

cd to Prima directory.

Type perl Makefile.PL

If everything goes well, type make

If everything goes well (previous step is likely to take several minutes), you can, if you wish, type make test and make install. You can also try PRIMA without making install; in this case it is required to set your PERL5LIB environment variable to point to Prima directory.

Try to run samples provided with the package. They are located in the examples subdirectory. Run them as perl examples/filename.pl.
