For people who are looking to use some sprites for their games Kevin Haag created the answer for you. He made a cool library containing many sprities that you can use for your games, they look very good, and all Kevin asks is that you give him some credit when you use them. Sounds fair to me, thanks Kevin!
Comments from the author:This is the second of my Isometric Sprite Library. It has a few new tiles and quite a few new variations of sprites from the previous instructions. Click here to download the sprites and read its comments.
