Fantasy Grounds is an application acting as a virtual online gaming table primarily intended for pen and paper style narrative role playing games.Fantasy Grounds is designed to perform many of the things you can do while playing at a conventional gaming table and move it online.Run games as the gamemaster or take part as a player, the application provides all the necessary tools to communicate, manage information and perform tasks such as rolling the dice or creating drawings.
This is the most fancy character sheet I've ever seen for TS/SI.
