Upside-Down
The upside-down drawing is a right brain exercise. If the picture was right-side up, the exercise of copying it would have been a left brain exercise, but turning it over couse the right brain to become engaged. A second part of the exercise was to time yourself. My time was 20 min and 30 sec. Initially I have a hard time figuring out how to start, but it became more interesting once I got going and the 20 minutes went by very quickly.
