Subsurf or "Subdivision Surfaces"

	Step 11 - Using subsurf is very simple: just click on the "SubSurf" button in the "Mesh" box of the edition menu (F9). As you can see, a rounded shape appears inside our mesh. On the latest versions of blender, there are 2 different algorithms to create this subsurf (subdivision surface), "simple subdivision" or "Catmull-Clark". I think the "Catmull" one is better, so keep it selected. You can also specify the level of subdivision displayed on the 3D view (and in "Real-time", but there's no real time engine in the Blender versions between 2.26 and 2.32) and in the render. The higher this level is, the better the result will be, but the more time it will take to render.  I think a level of 2 or 3 is high enough for our octopus.
	Step 12 - Now all we have to do is press the "Set Smooth" button (still on the edition menu, in the "Link and Materials" box). Then enable the shading with the Z key to see what it looks like. Note: If some of your tentacles look weird, this might be because you extruded some part of it without moving the points created by the extrusion, and then extruded over again. This causes some points to be superposed. To remove them, select all (A) the points, and press the "remove double" button, as in step 10).
	Step 13 - In the Shading menu (F5), click on "New Material", and define a color for your octopus. This is not supposed to be a realistic octopus, so I made mine a light-blue. :) Now the octopus is almost complete, but it lacks eyes. Note: If you're tired - or if you don't want to add eyes to your octopus - you can stop following this tutorial here.
	Step 14 - Switch to the object mode (Tab). On the top view (1), and on the same/new layer (as you wish) add a sphere ( Add > Mesh > UVsphere). 20 segments and 20 rings should be just fine. We're going to add 2 materials to this sphere to make one eye. Go to the Editing menu (F9) and click twice on "New" to create 2 materials for this single sphere. Then, go to the material menu (F5) and click on the "2" that is displayed on the right of the material name. Then click on "Single User" to validate.
Step 15 - Go back to the Editing menu, and (with all the points of the sphere selected) click on "Assign" (below the "New" button). This will assign the selected material ( material #2 of "Material.001" in my example) to the whole sphere. Then deselect all the points (A) and use the selection circle (B-B) to select the points in the middle of the sphere, as shown in the image below. On the Editing menu, click the left arrow of "2 Mat: 2" to select the other material we created (It should now display "2 Mat: 1" ), and click once again on "Assign".
