This thing's pretty cool. It's a Flash MX enhancement on the standard listbox control. I made a suggestion for improving it's usability though:

"This is cool. I do have one usability suggestion though: The fish eye effect only responds to the mouse. If I focus the list and am using the keyboard to jump to an item in the list, the selection jumps, but the fish eye effect does not follow. I believe that it should as I might want to use alpha-searching to scan the list and I need to see if I've hit the selection I was looking for."

To be honest, I'm not a big fan of Flash. I've created plenty of functional sites using standard DHTML and more recently SVG. I prefer sticking with those technologies because they are based off of XML and the DOM which means my knowledge of XML as a technology is transferrable between the two higher level technologies at an abstract level. Never felt the need to learn a proprietary object model and development environment. Granted they've opened up the file specification now, but I don't think it's going to make much of a difference... SVG has come a long way and is gaining industry support everyday.
