We have a few decades before the most eager transhumans get to merge with the robots, but in the meantime there's no harm in pretending. The God Ability LED wristbands allow you to accessorize any outfit with moving LED message screens that give the appearance that maybe there are gears and microprocessors powering you rather than Instant Ramen and Diet Coke.
You can input up to 255 characters with six different messages and the device accepts English as well as Japanese katakana characters. If fashion appeal isn't your thing, then the company's name alone should be enough to peak your geek interest. Both versions are available online for 3,480 yen ($31.45) here.
