An Open Door
An open door was an obvious metaphor. We as a team wanted to create an emotional response to the information presented, which we believed would inspire a pro-active stance to the information, not just a view and forget mentality.
I never really liked the old style of a training / information video with a blank screen and an outline intermittent with live action. When the word SPOTTING faded in, the door slowly swung open as to invite the audience into the same virtual space as the information being provided.
