Yes, you can do that with a Euro 10.000 up Hog, but with some effort 
it can be done also with the LanBox :-)

First off all to fade-in your your circle chase, use the same trick 
with a transparent layer. Instead of an all zero cue use your "center 
cue", and let it fade the transparency to 100% (your running circle 
chase.

BTW By changing the transparency by hand you can dynamically change 
the size of your circle path:-)

Make a control cue to start and fade-in the chase, and another one to 
fade-out and stop it:

To start chase 99, run 10 in any other free layer.

 // Cuelist 10 (2 steps), modified 22-01-2007 19:13
  set layer A to mix transparent from 100% to 0% in 10s
  go 99.1 in layer A


To fade out and stop a chase in A, run 11 in any other free layer.

 // Cuelist 11 (3 steps), modified 22-01-2007 19:15
  set layer A to mix transparent from 0% to 100% in 15s
  hold for 15s
  go 0.0 in layer A

Now add another layer below the transparent layer, and put it in Add mode.

Let a cue running in this layer with the values 127 for the pan/tilt 
channels only (127 means 0 for Add layers). When you change the 127 
values, you will see that your path gets a different location.

So in order to get a moving path resized and positioning, you need an 
transparent and an Add layer. If you search our archive you will find 
e.g. this:
