 # Notes: 
-# - There is a cube that spawns amongst the grid that doesn't fit in with the rest.
-# - To create the grid to spawn cubes in the z-axis, then I should create a new for loop within the nested loop to take create it in the z-axis. 
+# - For loop for the grid: 
+#        - x is for creating cubes in the x axis. 
+#        - y is for creating cubes in the y axis. 
+#        - z is for creating cubes in the z axis. 
+# - I need to add the materials to the cubes and somehow save it in the Blender program.
