Run the following in the terminal. 

git clone git://github.com/illuminate/app.git && cd app && composer update 

This will download Illuminate (the name of the component set that makes up Laravel 4) into a directory called 'app' and run composer to get all the dependancies. 

Of course, it's still heavily in development so it's clearly not finished but you can poke around and see how it works. Enjoy!
