Cool pattern on driveway

Any idea what would cause this. I though maybe it was from the cultured stone on the wall.

Groovy, man. Trippy. Far out.

I have no idea whatsoever.

I think I have it narrowed down to 2 possibilities. Dye from the cultured stone of someone peed on the driveway.

Brian beat me to it. Covering freshly-poured concrete with plastic can cause patterns like that.

Ditto. I've seen it from covering concrete with plastic.

I've seen this pattern when plastic sheeting or insulating blankets are used during the first 7 days after concrete placement. The pattern mirrors the contact between concrete and plastic or air trapped under the plastic (wrinkles in the plastic sheeting).
