Cool
Okay, a little inside about the job.
I know you guy's like to look in the kitchen

Lets start with the "control art"

I created a arrow with 2 basic objects, a retangle and a circle joined together, copied it 2 times, rotated them 45 degrees and stitched everything together.
the tank is build up from rectangles too wich are also stiched together so it is one compound path

Then the "rotate" indicator:
two circles with the correct dimention are the base..

I sliced them up at the "bottom" of the arrow, and added triangles as arrowpoints
deleted the parts after deviding it that where too much..

And this is the result after exactly centering everything and changing the color to white..
Later i will cut them out of the orange so the orange will be a compound path.
Later more my friends
