I don't make claim to the art work for these skyboxes. That credit goes to other talented people who allow you to use their wonderful skyboxes. My part was in finding these skyboxes and putting them togeter so to be used in the Active Worlds browser. The pictures below show the front, back, left and right textures. I don't show the top textures but it is included in the download.
