Just for kicks really, it'd be nice to have a logo for unl0kr even if just for using in the README. As a quick idea, we could transform the upper end of the "l" into a key and the lower end of the "0" into a lock, as demonstrated on this quick mock-up:  The key-l and lock-0 could be colored differently than the rest of the text maybe to make them stand out. Cropping the logo to just the key-l and lock-0, we could also create a square variant of it for use as an icon. See also cherrypicker/buffyboard#8.
