Hamilton, Im sorry to say this, But as ingredient said, This tutorial just isnt helpful anymore.
1. Im pretty sure 2.59 does NOT have the grid button!
2. Without the grid button, We cant load any scripts im quite sure of it.
3. This is quite hard to follow, Since theres a lot of things removed in blender 2.59.
Not trying to tell you what to do, But im just suggesting something here.
You may want to get the newest blender, And just make a tutorial for it. Im pretty sure we cant even GET the old python anymore, And so, Even if we did have the old blender, There wouldnt be a python to work with it.
See my problem here, Hammy?
