I made 100 logos in 100 days. The only rule was that I didn't spend more than 100 minutes on each logo (that doesn't include thinking about the logo). The logos were made fast, sometimes rough, sometimes even drawn on paper or palm of my hand.
Logo themes vary. Whatever came to my mind - I made it into logo. Some logos might be more of an illustration rather than standard logo, and some might not be full professional logos with every aspect well thought, but I allowed myself this freedom. Bare in mind that I had only 100 minutes to produce (I hope) an interesting logo. Idea is what counts here more than realization, I think.
Some logos will be specific for my country (Croatia) and in my language. I will try to explain every logo the best I can so you could understand the concept.
You will see a lot of Westie logos. I love West Highland terriers and I have one for my friend. He is my constant inspiration. Unwritten rule was that I made every 10th logo (or so) with a Westie as a theme :)
I started this project on October the 4th (on my nieces 1st birthday) and it was over on 11th of January.
