I got inspired this year at the 26C3 in Berlin to code a game called hex.
This is my Multi-Touch game prototype, open source and free download coming these days.

You can play it online @ www.31media.de/hexTouch (If you have a Multi-Touch device: hex connects on port 3000 an requires a running flosc server.)

“Hex is a board game played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus.

Each player has an allocated color, Red and Blue being conventional. Players take turns placing a stone of their color on a single cell within the overall playing board.

The goal is to form a connected path of your stones linking the opposing sides of the board marked by your colors, before your opponent connects his or her sides in a similar fashion. The first player to complete his or her connection wins the game.”
