I modified my LEGO AT-AT walker model a bit and removed the storm-troopers that where sitting inside (who are obviously very incompetent, because they can't even make the walker stand up again after it drops to its knees) and made replaced them with a Raspberry PI.
Now I have an AT-AT-Walker Raspberry PI Lego case - Very awesome :-)
