Countdown timer.

I am doing a video tutorial that will ask a question then pause 15 seconds or so then display the answer. What I need is a timer that will count from 15 on down. ? Maybe display in the bottom left corner (viewable) .. It will need to be small enough that I can have most of the video room for text but big enough to still be read from a slight distance. I will need to be able to import this in to Final Cut Express 3.5. I will need this tonight, next couple hrs. Thanks. ## Deliverables Need it in a format that I can directly import it in to final cut express and the source it was made in, flash, etc.
