[more stuff deleted] Yanek - Recently (a couple of months after the TI system was demonstrated) a researcher here at Canterbury Uni. had a similar system using commonly available C.R.T. parts, with a couple of electron guns firing at a rotating phosphor plate. His system cost somewhere under $1000 NZ (I think), but he was having some trouble getting funding (isn't everyone!), so I don't know if he's continued with it. Send me some e-mail if you'd like me to dig up some info, and I'll see what I can do ... Geoff.
