Hi Evan, There's a company making a modern Opticon improvement--it's a little square display, and you use a camera and the images go through a computer and display on this thing in raised dots. The demo I saw involved a map, some print, and--oh glory!--an honest to goodness maze game! Pricetag? Hey, if you have to ask, you can't afford it--it was 16 grand for the better version. The display is a bit small for big pictures and graphs, but if you could handle panning across and up and down something and get the whole image in your mind you could use this thing for any imaginable purpose. I was most assuredly drooling! Kellie To unsubscribe from this list send a blank Email to bksvol-discuss-request@xxxxxxxxxxxxx put the word 'unsubscribe' by itself in the subject line.
