Bi-Direction Text Example:

Some text going from left to right
Some text going from right to left

This makes use of the <bdo> tag. This has one property, with two options:
<bdo dir="...">
ltr - Text runs from left to right
rtl - Text runs from right to left

Don't expect it to work in IE 3 or 4, or in Netscape Communicator 4.xx
