The opening screen should be kept very simple with just a panel to type the sum plus the ability to select the number of zeros added (e.g. million, billion etc.). The user should also be able to select different currencies. In the future a currency calculator can be added as a feature so the user can view any amount of money in his or her country's currency. | The opening screen should be kept very simple with just a panel to type the sum plus the ability to select the number of zeros added (e.g. million, billion etc.).

After confirming the amount the screen with the visualization will appear. A integrated calculator will split the sum in different categories, e.g. billions, millions ten thousands. Then for each category an object is chosen and the number of objects which can be bought from the entered sum is displayed. It is important that the user has a vague idea of what the object's price is. The categories are used to only show small numbers of objects. Otherwise the effect of understandable visualization will be gone. | After confirming the amount the screen with the visualization will appear.

For visualizing the money the example of real estate was chosen as presumably most people have an idea of the value of a house. The categories in this case are city (all real estate within a city of one million inhabitants), apartment buidings (a buiding with room for around 12 apartments), and family house. The value should be adjusted to the current price and the user's location. | For visualizing the money the example of real estate was chosen as presumably most people have an idea of the value of a house.

For the future the visualizing objects could depend more on what the money is used for. How many hospitals can be built with a country's military budget for example? | For the future the visualizing objects could depend more on what the money is used for.
