This application hides information about a photo (either the photo itself, the tag, or the person who wrote about the photo) and so it's important that we use powerful metaphors of Photographs (the "which photo" box), Human identities (the "who" box), and speech bubbles (the "what" box).
We only need very good graphic designers. So please include your portfolio as well as some mockups in your bid before we choose you.
It would be best if you could actually write the html for these designs.
