suggestions? I wish I could see magnetic fields! Short of that, at times like this I wish I had a magnet implant like this guy that can feel magnetic fields: http://www.wired.com/gadgets/mods/news/2006/06/71087?currentPage=all Thanks, Jeshua Lacock Founder/Engineer 3DTOPO Incorporated http://3DTOPO.com
