A Linear Triple N-Back machine.
----------------------------------
Platform requirements for Linux and Mac:
* OpenGL must be installed
* SDL must be installed
Also note that on Linux you must check 2 things: first of all, the file must be executable. You can set the file executable from a shell terminal with the command "chmod 755 your_file_name", or from a filemanager application. Plus, the engine looks for a lib called "libGL.so". You might have some other libs like "libGL.so.1" or "libGL.so.1.2" installed in your "usr/lib" folder. If this is the case, you can create a system link using the command "ln -s usr/lib/libGL.so.1 usr/lib/libGL.so". Root privileges are needed.
