 - Fast-ish (as fast as rendering on the CPU can be)
 - Portable! Outputs simple image files
 - Notebooks! Works well in the Jupyter notebook ecosystem
-- Eye candy! [Ambient occlusion](https://en.wikipedia.org/wiki/Ambient_occlusion), specularity, etc
-
-Known issues (TODO)
-- Speed: Need to migrate to a GPU-based renderer while maintaining portability (suggestions?)
-- Illumination: Light source ray tracing is wonky - but you can fake it (see light_source.py example)
-- Cut offs: The bottom of some voxel cubes are cut off - I'm not sure why
-- Likely much more...
