Thanks Chessmosaic for this breautilful AdaChess logo!
I choosed to use it as official AdaChess engine logo. For anyone who doesn’t understand the logo meaning, I will explain the idea. Ada is the programming language targeting at mission-critical software. That’s why the logo has a rocket there, ready to be shooted into the clouds, with chessboard pigmens as of course it is a chess engine. I like it!
