Q. How was this site built?
A. This site was built using the CodeIgniter framework for PHP and MySQL and also uses Adobe Flash for creation and display of drawings and animations. I can't recommend CodeIgniter enough for those for those with beginner to intermediate development experience, the MVC framework helps you organise your code while the light (and fast) libraries speed up dev time.
