hey thanks for the suggestions (last link not working Matt) I shall explore youtube some more too I thought it would probably be a waste of time . . .
so maybe there is some good stuff out there on the other hand Terence Hill in a ninja movie is also a great find I should probably dig out those Stephen Hayes books I bought at the local supermarket when I was a kid and see if my fingers might have become more flexible through playing the sem . . .
(definitely a great book is essence of ninjutsu by hatsumi available at amazon)
anyway hey this clip is actually cool not to mention it features a hot kunoichi 
Happy Halloween everyone . . .
