Before we roll down this road, (and it looks like it just my be the right way to go), Maybe there is a better alternative.
Its just that, I would really like to see this become the best and most played map at CC. I do not think that this will be a very easy map to play. At a glance it will be difficult to read what is going on in the game. That in itself, is not necessarily a bad thing for a map, but, it may turn off those that just don't want to expend the brain power.
I have an idea that would solve this riddle, but, I do not know very much about HTMLs' and what supports what. I do know that it could be done. I just don't know if they would want to write the code or whatever it is that they do.
If you have been to Google Earth or the like, You will see the answer right there. Simply have a gif with a few frames of the globe as it turns. A slider bar or whatever can be used to turn the globe. you simply stop where you want. This allows us the opportunity to have twice the area for our map without increasing the size.
Hey if this stuff was easy, the girl scouts would be doing it.
