Making Spirals

Here is another one made by starting at the outside and working inwards:

Here are the instructions to draw it:

Take an A$4$ sheet of plain paper and put it on your desk so that the longest side is horizontal.
Fold it in half with a vertical fold. Draw a curve from the bottom left had corner to the fold line.
Halve the right hand half horizontally and continue the curve from your top to the new fold line.
Conitue in the same way repeating the halving and folding exercise so that your curve spirals in to its centre.
This spiral is different from the Golden Spiral and Archimedes' Spiral.
