Conclusion of Katakana and Hiragana study

I have recently concluded my studies of all the Kana characters. I know enough of them now to immediately recognize them all. Plus, with the two DS games: DS Bimoji Training and Kageyama Method: Tadashii Kanji Kakitori-Kun - Kondo wa Kanken Taidaku Dayo!, I am learning and writing new characters.

If possible, can someone show me how this site works: http://ajaxime.chasen.org/
