Or perhaps just bi-polar.
As for my encryption, I could give you a hint, or I could just tell you exactly what I did. Either way, I don't think anybody would be motivated enough to decrypt it. The first section is a list of coordinates. Each coordinate is made of two bytes. The first byte represents the low-byte of the x-coordinate, while the second represents the high byte. Same with the third and fourth for the y-coordinate. It translates into an unsigned integer, so any numbers above MAX_INT should be turned into their respective negative values. After all of the coordinates are found, use these as verticies, and the second part tells which verticies to connect by a line segment. It spells out the message.
