As a designer, I find myself eschewing tools that look and act clunky. I like to use attractive software that is kind to my eyes.
So when I started to use the Terminal for Web stuffs, I needed to find a way to make it appealing.
I found what I was looking for on Dribbble with Flat UI Terminal Theme by Ahmet Sülek. Download the appropriate attachment (there is one for iTerm as well).
Happy coding!
