Interacting with a source object via a virtual object

A non-transitory machine-readable medium comprising a plurality of machine-readable instructions that when executed by one or more processors is adapted to cause the one or more processors to perform a method comprising:

• associating, by a computing device, a first set of properties of a virtual object with a second set of properties of a source object, the source object being defined in a program;
• defining, by the computing device, a set of functions corresponding to the associated first and second sets of properties;
• receiving, by the computing device, a first request to instantiate the virtual object;
• instantiating the source object in response to the first request;
• receiving, by the computing device, a second request to perform an operation using the first set of properties of the virtual object;
• executing the set of functions corresponding to the associated first and second sets of properties in response to the second request;
• and
• updating the second set of properties of the source object in accordance with a result of the executed set of functions.
