Stumbled upon this tool a while back and signed up for the beta.
Its an in browser based app that allows you to create maps for use in fantasy games or really whatever. Anyway check them out and if you would like, post some of your creations in the comments. Above is a map I am working on as a way to get familiar with the tool. Fairly straight forward in its use and really happy with the results. I made the above in about 2 tries and 30 minutes. Im not affiliated with inkarnate in any way, I just think its really cool and so am sharing!
