Message-ID: <17924@agate.BERKELEY.EDU> Date: 6 Dec 88 22:00:01 GMT Sender: usenet@agate.BERKELEY.EDU Reply-To: hughes@math.Berkeley.EDU (eric hughes) Organization: UCB Mathematics Department Lines: 15 Could someone please explain what these GS devices are and how they work? I take they are some sort of electromagnetic positioning thing, but exactly what? I have often thought that I would like a light show type display instead of staring at a CRT all day. It seems doable to set up a scanning system which would continously redraw the letters on a wall, just like an old vector drawing graphics display. Ideally, there would be a card in my PC which would emulate a standard text card and would connect out the back to the display device. Ideas? Comments? References to previous work?
