Fun tool for the mappers

[Keero]

I found this to be extremely easy for me to get my mapping ideas on paper... uh, screen. You could have a basic map up in seconds, details could take longer. It's free, simple, and I'm enjoying it.

I believe this tool has also been used by people to make a map for inside their maps (can't quite remember for certain). That is to say they use it to make a texture of a mini-map and put it on the wall within their maps.

I've seen this around, but never actually used it. I might ought to look into it.
