iPhone App Icon - One of a few possibilities

One of a few design styles for the upcoming Sifter app icon for iPhone & iTouch. Also looking at flat colour opposed to the wood texture direction.

This is more about tactile dimension that untouchable hyper-realism.

An icon that just looks like you could interact with it, like poke your finger in the hole and wiggle it around underneath the wooden top.

The initial S will sit centrally within the dark inset of the icon which has a black rubber edging/seal around the beveled opening/hole.
