Powers of Ten Zoom
Choose an object you can see to be the focus of your zoom. Draw a picture
of what you see looking down on a 1 metre square surrounding this object in
the large box below. Use a ruler to make sure everything is drawn to the
correct size. The lightly drawn grid of boxes (each 10cm on a side) should
help you do this. The main object for the zoom should be centred on the
small dotted box in the middle of the larger square.
