This is an update to something I showed at AxureWorld. The question that lingered was why the animation worked in IE but not in Firefox. As predicted, the problem was Firefox and it's darned speed. Adding a 10 ms wait between each animation step seems to have cleared up the problem. Of course, it's now slower in IE, but you could adjust as needed.

Note that I designed it to track daily hour allocations, so no column should total more than 24.

Anyway, this is more fun than useful, but I'm putting it out there for those who want to delve into how such things might be done. Things worth noting: 

• It's an example of the focus-chaining technique.
  
• The bars are nested panels--think of them as telescoping antennas.
• The spreadsheet cells seem to allow you to edit plain rectangles, which is kind of fun, and even support tabbing from field to field (but only forward, sadly).
  

 Enjoy!
