Original SeaBlock updated to 2.0. Unofficial fork of KiwiHawk's Sea Block (MIT), fixed to run on Factorio 2.0 with current Bob's (2.1.x) and Angel's (2.0.x). Also adds a stone-based pipe recipe.
Darkenade, Since your "Sea Block Continued" is MIT license, it would be nice if you open source your code instead of linking to KiwiHawk's version. That way I can git clone 100% exact same code without having to download and extract mod file.
You can credit KiwiHawk in readme if that makes sense.
