In the department of the new and cool, you should check out the videos of John Grden’s FITC presentation (otherwise known as all the justification you ever need to attend a conference where John is one of the speakers).
Keith Peters just released a copy of his presentation on Apollo – it’s the best introduction to Apollo I’ve seen. Excellent work.
Finally, check out this cool scientific graphing calculator done in Flex. Nice stuff.
