I should know this but this is really neat (in a not so neat way).
Look at it in IE6 and any other browser. Hover over a thumbnail. In IE6 the border doesn't encompass the whole picture. I thought it was something like FF does but I was wrong. Click and hold down your mouse, now drag off the pic and watch the top border disappear but the bottom part apply the hover. And if you play with doing that you can actually get just parts of the border to hover. Sort of like a dashed border. It seems to only glitch on IE6.
under the thumb for "Clovis" there is a H3 for "Turkish Disco". In all other browsers it's spaced correctly. In IE6 it's snug up on the Clovis thumb. any ideas on that.
