Good luck with your procedure, Coolbreeze.
Recall we'd a short discussion on the fiducial markers and thought I'd update you. I've skipped that step as my doc is using a different machine. So I only have those tattoos you'd mentioned on your blog
and yes, I wish they're multicoloured instead of greyish dots now! Think I want my money back cos the black dye faded and they've turned grey, lol..
