Semiotics from a Newbie's Perspective

Recently in class we were tasked with finding five semiotic characteristics of an advertisement.  I chose an ad for the Hummer H3 that I thought was visually stimulating.  Let us see how we can break it into semiotics.

Can't you just hear Erkel squawking "Did I do that?"

1.  The signifier is the orange background.  It signifies a bright or fresh idea in the form of the Hummer.
2.  The signifier is the brush guard on the front of the truck.  It signifies strength and invincibility.
3.  The signifier is the bold font.  It represents boldness and masculinity.
4.  The signifiers are the periods at the end of the short sentences.  They represent a powerful statement worthy of absorbing one thought at a time.
5.  The signifier is the appearance of zero-gravity as the truck breaks through.  This represents the shock-value of seeing such an interesting new truck.

Alright, I hope that this is an appropriate basic analysis of some signified/signifier semiotics.  (Say that five times fast!)  Thanks for reading!
