how do i do this?
i want an icosphere, and i want to extrude each triangle on it to its normal, i.e. directly away from the center.
so i sort of want to extrude, and scale, but i want it to be attatched, so that when i hit subsurf i get an effect that looks a bit like the biomes in the Eden project.
does anyone understand what i mean? im having trouble putting it into words. i seem to recall someone made a picture that is very similar to what i want, but i can no longer find it.
thanks

I guess you mean something like this:

this is done with a script. just search for it. its in the plugins forum.
I think Alt S is what you want. scale along normal.
GFX, you need Andy Houston’s excellent, Geodesic dome script.
Available here:- http://homepage.ntlworld.com/andy.houston/
This will explian all.

Whatta :o ,
Thanks Sonix for sharing the link and especially to Andy houston, the creator 
wow man that look like a cool script!
cool!
thanks man
only thing is, after like 3 geodesic objects, it stops making them, it just gives me a small pink normal point.
ah well, thanks all the same guys.
GFX, I found that you need to save each new geodesic object as a new .Blend file, then use Shift F1 to append your dome into your current project.

Playing around today, I took a cube and in edit mode hit W then 3 for Subdivide smooth. Got a geodesic like figure on the first try at 100% and doing it twice I got like a perfect soccerball.
Try it, maybe you’ll get something you need.
