Lights in Copenhagen
Look carefully at the image above.
Make an estimate of how many light fittings you can see.
Now count them.
What do you estimate the total number of lights on the fitting to be?
How can you decide if your estimate is a good one?
Did others make better (or worse) estimates? How can you decide?

What else do you notice about the light fittings?

Now, look carefully at the rods that the light fittings are attached to:
  • What do you notice?
  • How many rods are there?
  • How many different shapes can you see?
  • Is the resulting figure regular?
