Because the Escape the Bus logo would be an iSchool Initiative product, I used the same font (Gotham Rounded) and the same green and gray from the company logo. The rounded letters worked well for the padlock in the mark.  I arrived at this clean graphic after exploring colors, connections, and playing on the words in the logo.

Designing the different logo versions directly on a t-shirt format helped me envision what it would look like in a real life application.
