Under Armour does a great job with page layout, and actions with the cursor. When going over a product, it shows another angle. The example below has a cursor over the first shoe, and we can see the other side. It is also very responsive, and when putting the cursor over a section on the nav bar, it automatically drops down. The only downside to this is if you are moving your cursor and it accidentally is over a section, the drop down will get in the way.
