A compiled Windows executable can be found at main/Tetris-Clone.exe
This executable can be run anywhere but make sure that it is always in the same folder as main/files (as that's where any necessary images and sounds are kept).
Main program is main/Tetris-Clone.py
Pygame needs to be installed in order for this to be run.
In order for the core modules to be detected, they need to be on the PythonPath. I believe that by importing the project into Eclipse (see eclipse-project.zip) this problem can be avoided. I use the Pydev Eclipse plugin for Python development.
This project was actually developed using Mercurial as version control system (see .hg folder).
