pinned head -noun
1. the face of a minifig appearing “pinned” on a backboard, particularly as portrayed in the form of a LEGO mosaic

I recently wondered how it would look to do a series of portraits of LEGO minifig faces, peeling away the normal look and shape of a minifig head, and concentrating on the face.  This series is the result.

So, does this make me a pinhead (definition #3 above) for making pinned heads? 😀
