The identity I designed for myself came about from playing with positive and negative space of letters. I decided to take it a step further and explored the negative space of the whole Helvetica Neue Bold alphabet. Disappointed with the I and the J, I had a look at some other fonts including Raleway Bold a san serif with a curvy J, and Century Schoolbook a serif with curves and terminals.
Here are the results, I also created stencils of the Helvetica and Century Schoolbook alphabet in upper case alternating positive and negative space letters. Which I have mocked them up as a cup and t shirt to see what they look like.
