My entry for this week's Industrial Design of the Week (#158) over at ConceptArt. We were supposed to come up with a robot that had wiped-out an entire planetary population. So instead of goin' with the guns & missiles routine I figured it would be cooler to have these robots corrupt and brainwash the aliens into extinction, have annihilation insidiously come from within rather than from some blaze of fireballs you could actually confront.
