viztracker + hand model

[cgibb]

Hello,

I'm attempting to show a visible hand on the screen at all times by using viztrack.MousePos() and viz.link. While it seems to work in an outside world (outside of my room model), it appears that the distance of the model from the pointer is much too far. I've manually edited viztracker.py, setting self.length = 1, but is there a programmatic/better way to do this?

Thanks in advance for the help.
