I´ve actually seen the fold-out cube type of test at a swedish military recruitment site. Go to
www.officer.nu put on headphones or a speaker and click away. Ya, it´s in swedish but if you´re going to be an almighty ATCO that shouldn´t be much of a problem, eh?
One hint "Starta testet" means "Start the test". Wait for the tests to load, I belive the cube test is the fourth and final. Have fun kids.
BTW, I got through the first stage tests in Sweden, will do part two in late april.
