I tried this myself and came up with something similar,
but the dithering in the Linus Torvalds image is
much subtler. My guess is that this was achieved
by using a plug-in (Photoshop?). I couldn't find
anything similar (at least during a quick search)
on the Gimp plug-ins site, at http://registry.gimp.org/.
Maybe someone else can find anything.

Greetings,

Claus
