This my husband's textbook that he uses at work. He's a computer scientist and he works at Volition as a game programmer. He brought this home one day and I thought it was a well done cover for a textbook ― especially a computer-math textbook.
The scanned colors didn't come our very well. The cover is more tan than the sickly green it appears to be and all of the adjustments I tried made it look more like puke. Sorry.
So, what I like about the cover... I like the shape and placement of the E and M and how they relate to the angle and triangle. The line represents a 2-dimentional vector (direction [angle] and length [magnitude]). Game programming uses lots of 3-dimesional vector matrix processing linked with velocity and acceleration matrices. I really like the geometric font for the word GAMES and the cut-away A. I could live without the swirly thing but I think it is suppose to represent the 3-D aspect of programming. All-in-all, I like the clean, angular, almost Swiss style of the cover.
