I have been messing around with the traffic textures to find some that work. There was originally a post by Dylan in 2/2008, referring to it, but it seems to have been deleted. Anyways, all you have to do is take any picture, make it a .png, and label it traffic.png, then put it in the textures folder, and voila, the car rectangle shape has been changed to whatever picture you've selected. It has some issues, as, they appear as square 2d objects, not 3d ones, and apparently, do not support transparency, but it is still fun to play around with. I don't know anything about programming, but I thought it might be easy for someone to make a simple one, to select the picture, convert if necessary (if possible), move it to the correct location, and label it traffic.png. Do you think it would be possible to add this functionality to your incredibly awesome program for the skyspheres?
Please let me know. :-)
