The Nature of Pencils

I had to endure an overly reverential worshiper of Great and Famous Photographers tediously ramble on about Fox Talbot's Pencil of Nature.

Yawn.

What fascinates me is the nature of pencils. When Sam broke the Motown pencil shaped like a treble clef I discovered there's lead even in the curvy part. After twenty years of photography, that seemed much more interesting.
