well actually, a "snaking" line is what I was looking for. Lets say the entire screen top to bottom represents 20 seconds. I would like time zero (now) to be 5 seconds from the bottom. This would give me a little history of what I was supposed to do and a 15 second window of what is coming up.

graphics is not my thing at all. I am a hardware guy that can do some logic programming (plc's). So, you will have to be the judge as to what will look good. Remember, this has to be smooth, otherwise the runner will get "sea sick" from the flicker.

Thanx
