Hi, here is my first design. I really tried to play on the name and your ambigram idea. Simply flip the word 'flip' to read 'life'. I know that you are also looking for a symbol to go with the name but I find that stylized type often does just as good a job. The word flip would simply be the symbol as well.
McInnis, my partner and I looked at all 3 designs. This isn't really the way we want to go, though I do like the idea of this being on a shirt, the main logo it's hard on the eyes and to be branded would be difficult since it's just a font.
If you are able to incorporate what we do like from the few ranked and perhaps make it more distinct that would be great! I do like the idea though and your creativity.
