The mouse-over effect on the arsenal page is extremely frustrating. Move the mouse away from the thumbnail and the info disappears. For balls far to the right or lower on the page, I basically can't see the ball, description, and thumbnail at the same time, meaning I can't see the info for those balls.
I'd either break it up into several pages (not optimal), or get rid of the mouse-over effect. Maybe have a text list, then when a ball is clicked, it shows in the info section.
BTW, this is using Camino on OS X. I know the three people who use that browser probably don't really matter.
