+Bugs
+====
+ * concurrent read? (concurrent write should not occur)
+
+Future Plans
+============
  * kd-tree:
    - optimize structures
    - optimize construction: do not use bounding boxes of shapes, instead implement box-shape intersection
    - save/load
+ * uniform grid, octree
+ * textures (3D procedural, pixmaps later)
  * update Python binding: Camera, new classes
- * more complex demos
  * namespace
- * refractions, glass
 
 New Classes?
