How to make crazy warped objects a.k.a Subdivide Faces and Change Fractal Number

Backface Culling

To be sure your model's normals are facing outwards instead of inside, hit the Backface Culling button that is located; under the 'N' toggling menu -> the one that starts with Transform on the top. scroll down towards the 'Display' section and check the Backface Culling box underneath the shading section starting with 'Multitexture'.

Now you can see the inverted normals and the holes in your model if there are any.

Next is the selection of your model. Highlight it in Object Mode and hit the 'Tab' key. You're in Edit Mode right now. Then press 'A' to select all the faces. If it doesn't turn orange, hit 'A' again.
Everything highlighted? good! Now press CTRL + 'N' , it automatically turns all the faces outwards.
