Just as an example

So, you know each block is 100 pieces, and I think I've said there are a LOT of blocks in this one (equating to an insane amout of pieces/piecing).

Here are the first few blocks together just so you can get a small idea of what's happening.

Above is a snap of the first three blocks alongside the portion of the pixelated image they correspond to.  Below is a close-up of block number four and the image I am matching to.  Well, actually, the image is to the left, and the piecing is to the right...but you get the idea.

Now, maybe, this will help to illustrate the enormity of the scale.
