"XNA" XNA is a set of tools Microsoft came up with for games development. The orange dashed line that makes up one of the ‘X’ strokes is actually Morse Code spelling out XNA. _.._ is X, _. is N, and ._ is A.
The logo for Microsoft XNA, a collection of tools meant to help video game developers, has an interesting hidden meaning. The orange and chopped up portion of the 'X' signifies "XNA" in Morse code. Here's how: A dash followed by two dots and another dash represents an 'X' in Morse code. Meanwhile, an "N" in Morse code is a dash followed by a dot. And finally, an "A" in morse code is a dot followed by a dash. Add it all together and you have XNA. Very clever.
