Meet the genius behind Japan's viral 'barely useful' inventions, who designs over-the-top contraptions for oddly specific needs — and earns a living doing it

• Kazuya Shibata, 27, is a Japanese engineer who makes what he calls "barely useful" inventions.
• His comical designs are often overly complex, but they've let him quit his job to do inventing full-time.
• Take a look at some of his creations, including a "business card launcher" and "toothpaste squeezer."

If Kazuya Shibata is remembered for only one of his quirky creations, he hopes it'll be his "Gorgeous Show Box."
