You're welcome! I'm glad you liked it. I don't often attempt a tutorial,
but I though it was sorely needed.

Nice. How did you model the streamer? Was it similar to your TC model
presented in one of your papers or a totally different model?

Yeah? Well I live in Aus. so it's not so bad for me =)

Yeah I liked the photos of your $$$ stuff =) I'm hoping to find another
cheap CRO and there you go with yer 'fancy' stuff =) I'm glad you like to
publish your results though... It gives us something to read =)

I like to think that there is a practical use for everything, if only we
knew what it was...
