Non-geometrical Shapes

A lateral thinking concept that moves beyond standard geometrical patterns to constructing new patterns in complex situations, illustrated by the puzzle of describing a milk bottle with half a pint of water.

THE IDEA

Non-geometrical shapes

Having used the geometrical shapes to illustrate the deliberate search for alternatives (and also the possibility of such alternatives) one can move on to more complex situations. In these more complex situations it is not so much a matter of picking out standard patterns as alternatives but of putting things together to give a pattern.

When to use it

  • Creative brainstorming sessions that require novel combinations of ideas

  • Analyzing ambiguous situations that do not fit standard patterns
