Hi I have a question, well if macmullin wished would it be possible to use Rte encoder or something similar with alist of where all the pieces are to be found and release this awesome project for use. I am not asking for myself but I know how useful something like this would have been had I been studying for my nursing qualification now not 10 years ago. just a thorght I am impressed I was thinking only last week when I was 'playing' around with the p4 skeleton in a graveyard how bad it looked even as a prop. thanks again Dave
