The animations show instances of the theoretical components of the idea
of ‘roundness’  dimensions one through four.
The first screen represents onedimensionality. The radar screen demonstrates
how the onedimensional form of a line, as it moves in a specific way
over time, describes a circle. The full circle is never present at any
one time. But through persistence of vision, we perceive a complete
circle.
The second screen uses a homage to Rothko to exemplify the circle in
its twodimensionality. Here, instead of a rectangle, a circular surface
is divided into colour fields. The colours of the background and two
sections are determined by projecting the height of the section onto
the colourwheel.
The third screen shows the Berlin Television Tower, the ball of the
rotating restaurant representing the circle in its threedimensional
form. Each frame is, of course, only a twodimensional representation
of this sphere. But again, through taking many pictures from different
perspectives and animating them, our perception automatically recreates
for us the threedimensional object.
The fourth dimension is more difficult. Mathematicians may be comfortable
working in fourdimensional geometries, but because of our nature as
prisoners in a threedimensional world moving in a specific direction
in time, no one can directly perceive a fourdimensional object. Imagination
is therefore necessary. Just as a threedimensional object casts a twodimensional
shadow, it is theoretically possible to create a threedimensional object
which can be interpreted as the ‘shadow’ of a fourdimensional
object. This is a 2D animation created using circles and ‘holes’
which leave a trail as they change size over time.
