Mention "Flash" and people still think back to 1999 and 2 minute Flash intros. Yes they are still requested, but today, Flash is utilized more subtly behind the scenes. We have the experience in using Flash to create a level of interaction unattainable with static HTML.
Flash can also be used as a tool for learning. If you have a product or service that it difficult to explain in plain, static text, an interactive Flash tutorial is ideal to get the point across.
