An easy way to focus attention on the turtle that is moving is to either change colour or size, or you can print out the something when the turtle moves. Something like this:

ask turtles
[ ifelse patch-ahead not any? turtles-on [patch-set patch-ahead 1 patches in-cone 1 120]
  [ set color red
    forward 1
  ]
  [ set color blue
  ]
]
