Although the tags weren't immediately compelling to me, the title caught my attention and after reading it I must say this story has a good deal of potential, partially depending on how far you're planning on taking it.

Any clues on how big across the 'pins' are going to get? An inch? Two? Four? Or even more? After all, bigger is better, as they say :)

In any case, the story so far is well written and I'm looking forward to its continuation.
