There is nothing wrong with the new 0.16 concrete graphics.
Except that they're not concrete graphics.
They look
- Nothing like poured concrete.
- Way too busy.
- Hazardous to run over.

This mod brings back the clean old 0.15 sprites, converted and tweaked to work with the new system.

"Glitches?"
Everything looks totally acceptable imho, but some transitions are a bit weird. Due to the changes Wube made, you can't just copy and paste the old images, and I had to make some crude hacks. Hopefully someone with more graphical expertise can help me out.

"The name is stupid."
Sorry.

"It's low res!"
It is, because the old sprites never had a hr version.
