Looking for a little inspiration for your Halloween costume? Then you might not want to read any further, as you'll likely only find yourself struggling to match the Samus Aran costume that 11-year old Joseph DeRose and his father are building. That costume apparently only consists of an arm cannon at the moment, but it's certainly an impressive arm cannon -- it packs an array of LED lights with various settings (controlled by an Arduino, naturally), not to mention an assortment of sound effects from the Metroid games. Those not concerned about being upstaged can check out a video of the build process after the break.
