I usually show them the map when all is said and done, though I've been trying to find an economical way to start printing for gamenight. Pretty tough to do with 30x30 color prints being somewhere in the neighborhood of forty bucks at the local printshop.

I really enjoy doing the water that way, I think it conveys a sub-surface current pretty well. I've been tweaking it for a little while, which I suppose is evident from levels 1-3 of this particular map set, with Whalebelly somewhere in between. Glad you're finding some use for it!
