Bob I wonder if you have done any experiments with graphical interfaces with JS. I think I probably have something roughly equivalent in function but on a completely different architecture but have stopped short of trying to do a graphical display because I have to severely limit the time I spend on hobbies at the moment. I have just used plain old JS and Ajax and get a reasonable scroll rate with frequency but I'm not sure what refresh rate could be achieved with a graphical display and whether it would be very different on different browsers. If you plan to do anything in that area I would be very interested in how you get on.
