Hey there!

Glad to see you've picked this up. I actually saw this mentioned in some reddit post a few days ago, and had already gotten a local copy to run in v0.18.x. I was thinking eventually the Algae Pit and Filtration Plant graphics could use updating. For my capabilities these are pretty lofty goals, but I figured I'd throw it out there.

Thanks for this, I've always been curious to try SeaBlock, but have always shied-away from the full AB mods, etc.

I want to update those images, but we dont know how to draw the image and dont have any idea of that.
if you give us those images, we will discuss and update that
