A method ( 800 ) is disclosed of producing an instruction set for rendering on a graphic display ( 114 ). The instruction set includes a plurality of time containers ( 502, 503, 504 ) to be rendered, with each time container ( 502, 503, 504 ) containing at least one timed element to be displayed on the display ( 114 ). However, the instruction set must obey a rule forbidding a time container ( 502, 503, 504 ) from referencing the content of a different time container ( 502, 503, 504 ). The method ( 800 ) starts by adding ( 802 ) an attribute ( 505, 506, 507, 508 ) to a particular time container ( 502, 503, 504 ), the attribute ( 505, 506, 507, 508 ) being associated with an event, the event being associated with a target element contained within the particular time container ( 502, 503, 504 ). Correspondence between the event and an effect on the display of a further time container ( 502, 503, 504 ) is then provided ( 803 ), in a manner consistent with the rule.
