What is a rye bread and what not?
What is a trolleybus and what not?
The idea is what can all those things represent, if you make creative use of it in a certain way.
Example: A rye bread can represent a trolleybus box, together with all the internal seats, wheel and the driver. This means automatically you can have 100 different trolleybusses if you want, not only one, you have to do all youself, like defining the size of wheel, head of driver, rod trolley.
What else can rye bread represent? Same for pita and white bread. This should be an eagle eye view to the bread world and its general flexibility. Thanks.
