Thanks for the heads up, I would like a minor correction though. My light staff was a bit larger and not designed for being swung around at all. The guy with the POV staff was a completely different project and a hell of a lot more complete! Mine only did a rainbow chase and got rather fragile by the last day, but that's what you get for building it in a hurry in a field!

I had a fantastic time building it there and I'm glad I did, as I got so much interest from passers-by who saw me actively hacking a project together.

I've also got to give a shout out to Mark Barnes, who's help was instrumental in getting the staff working at all.

oops. I can see that now. I have quite a few pics of your project. I'll let Shane know.
