Hey, is it Image Ready?  The program you use to 
get the images to do that?  I know Adobe Image 
Ready is great for web art, and perfect for image 
slicing in just the right places.  I only use it 
for minor things at work, but it seems that it 
could be used for something like this.  I need to 
teach myself some more on it.  I do admire the 
way you get the graphics to do that though, I can 
never get stuff to line up >_>~~
