This is the volcano on the far side of the Island, that will eventually be active. This was a fun part of the exercise, as it showed how quickly the environment can be altered and brought to life. The volcano only took about 10 minutes to raise and paint. 

This portion of the exercise was where the light source was introduced. Unity has a built in flare source to model the sun. All of the shading caused by the angle of the sun in relation to the landscape is automatically calculated by the engine. 

I just entered the scripting portion, and will be working in Javascript. Unity also supports C#. I did a rough build of the Island, and can already walk around.
