Why Maya. To be honest it is just because Maya is a shade of blue and a cool name. And yes Mayas were very sophisticated in their time and according to ancient standards. We like to think that our skin is sophisticated too
I have just sent a PM to some of the volunteers that wanted to test the skin. We limited the number of testers, as the three of us all have to do the work besides real life jobs and/or children, and therefore have limited possibilities to respond to feedback (no matter how much we appreciate it!)
If you didn't get a PM, don't worry, as we get closer to release we will accept feedback on a large scale
Our target is still to finish it at same time or before MP 1.1.0 final.
