For those who care, the POP image above consists of:
First P: The P from Potter in a "Harry Potter" poster. This P represents the movies/entertainment component of POP.
O: A Compact Disc. Represents the music.
Last P: Part of a pottery inkwell found in the first century B.C. This P represents the literature/print media component of POP.
The purple background is a modified bubble wrap image.
I got bored of the old template.
