Number banners have been used to explore issues of time and motion. Their dynamic qualities are shown to their greatest extent when they are used in conjunction with cardboard arrows.
Number Banners do not just act as dynamic tools; they have a personalities of their own. Below is a description of Number Four Banner, which was shown alongside the Number One Banner sculpture.

"Number four banner

This banner is one of the first in the number banner series to have an identity that is less to do with its order or position in the banner group and more to do with its higher numeric value.
Four is an even number and is two squared. Most of us have four limbs, cars usually have four wheels, this supports an impression of stability within number four.

As well as being symbolically stable four banner is sturdily built. Four is just outside the initial 1, 2, 3 banner sequence."
