Once again TeeFury (http://www.teefury.com/) offers an heraldic tee shirt. This one for Star Wars fans and, as always, is on sale for just a single day.
It’s an interesting design, but really the only heraldic thing about it is that it is on a shield. Unless you want to count crossed light saber hilts as being heraldic. (And crossed weapons - swords, axes, etc. - actually is a pretty old heraldic motif.)
Blazon it for you, I will not.
