Grading icons

We need an icon set that runs from A+ to F, with all the ranges in between, but each one needs to be textured differently.

We'd like a fun, quirky play on a teacher's grading marks. They'll run from A+ to F, with all the ranges in between (A+, A, A-, B+, etc.), but each one will be textured a different way. A+ will be diamond studded, while A will be gold, B will be silver, C will be bronze, D will be tree branches (? or some other suitable metaphor) and F will be dirt. The + and - signs will be a bridge to the next material. For example, D+ would be a D made of sticks, and a + made of bronze. The style needs to be (for lack of a better descriptor) web 2.0. Inspirations include the Crystal Icon Set, located at http://www.everaldo.com/crystal/?action=preview.

Let us know if you need clarification.

We might have more icon design projects in the future; we'll be more willing to award those to the designer we pick for this contest.

Thanks! :)

Love, Receet

- Fun, whimsical
- Web 2.0
- Stylistically similar to the Crystal Icon Set, linked above
- Polished, slick
- Preferably in a PSD
- Or, if not in a PSD, then in a transparent PNG in different sizes - 16x16, 48x48, etc.

- Flat designs
- Lack of attention to detail
- Something that doesn't fit in with the above mentioned set.
