I did the dot thing last night too 5cm,10cm,15cm and 20cm at 20% to improve my aim and control. I usually do a few exercises for about an hour and then have a play with an eye or flames or last night "space, the final frontier". I'm improving slowly but I still have a looooong way to go, but hey, the only job where you start at the top is when you are digging a hole so on with the practice. HeathD
