Tatsuya Matsui is more widely known for his designs in robotics but he has foraged into the world of office supplies with the Kokuyo X-ViZ Calculator. Don’t be fooled into thinking that this is actually a television remote control in hiding, because it’s not.
There are a million other calculators out there and some can probably out-perform the X-ViZ, but what makes this gadget so different? For one, it was designed to be used with one hand only; hence, it’s ultra slim shape and sleek form.
The Kokuyo X-ViZ comes in classic black and basic white, so take your pick. Unfortunately, they will only be released in Japan but you can contact Rinkya or Flutterscape ahead of time if you want to order one. They are priced at ¥5,250 ($64) so they aren’t exactly cheap. But if you’re a lover of calculators or all things quirky, then the X-ViZ is probably worth every cent.
