Uplift is a toy-box. Each of the components can be thought of as a toy from a compatible set. But it is also software, and some things rely on other things in order to function. Trees, for instance, need water to live. If you tried to play with trees without the concept of water, you wouldn’t get very far.
In order to simultaneously provide toy-box freedom alongside robust dependency visualization, while staying true to the nested voxel presentation, I decided to structure the component dependencies such that they form a voxel structure. Each block relies on all of the blocks beneath it.
