Tsumani tute redone from AS.org

Alo all

Just been reworking the Tsumani flash piece tute from AS.org, updating it with the latest code and etc. Seems to work fine (although it would be nice if the text slides up into position in the background as well).

Also not to sure if the code is clean enough, can someone have a look and let me know how to make any improvments to it?
