Sensei Mark,

Just wanted to drop you an email to thank you and all the Senseis for their terrific work with my son, Philip.  He's learned so much, and I can't imagine how he would be without the training your school has provided to him.

I also wanted to thank you for helping me out with my work as a scientist.  In our laboratory, we study people's movements through a space, that is, their locomotion.  I was inspired by your chalked sword technique from the "Samurai Skirmish" at the beach and was able to develop a new research paradigm for our experiments. That is, we have a computer record people's movements while they are avoiding being chalked by foam swords.  It's been a tremendous success and a great advance for our field of study, and it wouldn't have happened except for Philip's taking classes at your school. So thanks again for your teaching and inspiration.

Sincerely,
Dr. Elizabeth Mezzacappa
