My "dream client" would be NASA. Hands down, top of the list. I would really enjoy being a part of something I believe so much in, being that of space exploration and the pursuit of understanding the mechanics of the universe. Greater still, bringing back that sense of enthusiasm toward NASA that I remember as a child.
Taking references and designs from my childhood, ie. FisherPrice space toys, LEGO and other things, I created this line of unofficial NASA mission patches in hopes of catching their attention.
