just an old drawing i have lying around here... maybe i should work on it a bit more? It isn't refined at all, but maybe it's an interesting idea, if i find the time i'll try to build one
it uses that jet thinggy just like cathar's block, that would help to spread the water over the different rows more easily imo... (this is a small block though, inteded to be 50mm by 50mm, no idea on the height)
