It's a script for an ad by a computer company for a new technology. A Flash animation ad. End-cap animation (for that technology) is the title of the document describing to producers all that's in the interactive ad. Attract screen and attract loop refer to parts of the animation, at the beginning, to attract people... This beginning is also called attract level... I wrote "Niveau d'introduction" but I'm not happy with that.
