I know that Matt Mullenweg and Matt Thomas die a little each time they see WordPress fan art that uses a faux logo. I only notice the chubby W because I’ve been edumacated.
MT (the real) has updated WordPress.org/about/buttons with official WordPress logos in pngs and vector image formats.
WordPress Logos and WordPress Buttons
There are also WordPress desktop wall paper in various official colors and sizes. The official WordPress colors are given in a variety of code systems. Pantone 7468 anyone?
Fan Art
The fan art page could use some fresh contributions.
These naturalized WordPress logos would be nice additions:
WordPress India Independence Logo by Allan Fernandes
One or more of the WordPress Malaysia Independence Logos by Avijit Paul. My favorite are the one’s with the flower for the O:

What is your favorite WordPress art?

Anyone know the creator of this popular images?

Same day correction: previously the article suggested the font is Dante, but both Matts have come to my rescue. It used to be the WordPress logo font. When Jason Santa Maria designed the new logo a few years ago, he chose the lovely Mrs. Eaves.
Adam Freetly identified the creator of the “lens flare” logo as being Dan Philibin.
