I found a great website about perlin noise and I have being trying to do it. A little bit down the page, it describes a way to add different levels and amounts of noise together to get a smooth line.

The website is http://freespace.virgin.net/hugo.elias/models/m_perlin.htm

and the code is

Graphics 600,400,16,2
Dim pass1 (2);128
For p = 0 To 2
	pass1 (p) = Rnd (0,128)
Next

Dim pass2 (4);64
For p = 0 To 4
	pass2 (p) = Rnd (-32,32)
Next 

Dim pass3 (8);32
For p = 0 To 8
	pass3 (p) = Rnd (-16,16)
Next

;Dim pass4 (16);16
Dim final (128)

Thanks Charrua, you really helped
Also "Paren el mundo!(me quiero bajar)" translated means stop the world!(i Want to get off)"
Sounds like your planing to stop the earth's rotation and go to mars while leaving us to freeze or burn on earth!

Well known here in South America, particulary in the "rio de la plata" where i live.
