Real Underground gets Flash right
Yes, I get crank when I experience Flash in places it fails (like the Macromedia site for ordering and their Forums for the tip of a very large iceberg), but there are some things that Flash just kicks ass. Experience the The Real Underground an interactive display of Beck's original London Underground map, the current map, and the actual geography. This Flash experience shows what would be very difficult to do otherwise.
Another good use of Flash is Gabe Kean's portfolio site, which scripts the pointer hand to only show over what is clickable, the site is meant to display past projects (and does it very well), and provides a good interface. One thing that does bug me is Gabe's address and other info one may want to grab for easy use in a PIM has to be retyped by the user, which greatly increases the ability to transpose info. Yes, I know this info can be lifted for unscrupulous means, but...
