I've been part of graphic arts communities for the last 10 years. Some large, some small, but all of them provided me with a place to learn how to use photoshop and manipulate anything with a computer. GFX Void, was one of the larger forums I have been a part of. It was so big that some members formed graphic teams and the different teams would "battle" each other to see which group was better at graphic design. My team was called Olympia, but we all wanted a logo design to put in our signatures so I made us one. I created a logo that contained the most famous piece of Greek architecture: The Parthenon. This might have been my first successful attempt at a logo.
Photoshop CS4, and a couple of hours.
