It’s a Lego, it’s a calculator, it’s all kinds of fun. Although I’d imagine it’s still not enjoyable enough to make people actually want to do math. In today’s world, if you really want to get some interest going, you’d have to create something like a breast shaped calculator that has 24 pressable, problem solving nipples. That would be money in the bank, my friend.

Is it a tape measurer?

Why, I would mortgage my house for a miracle, space-age tool like this. How much does it cost?

If you are out there trying to sell stuff, any little thing can give you an edge. You know the customer will remember you after you whip out your mini briefcase to give them a business card. While you are at it you can use the calculator to show them just how much money you can save them.
You can remove the calculator if you want, then you can fill it up with any type of contraband you choose. No matter what you are carrying, a miniature briefcase is the coolest way to do it.

Multi-tasking just got a whole lot easier (and more stylish) now that the MoMA store is carrying Naori Miyazaki’s Mobile Calculator. The thin cell phone inspired design looks great and it makes it possible to do your calculations using only one hand. I’m not too thrilled about the display, but it does feature a clock function—which is always useful. Then again, an actual cell phone has all of these functions as well, which makes this entire concept kind of redundant.

Uh, last time I checked most cellphones had a calculator built-in. So, you know…wtf. It does have a mirror though—so it is not completely useless.
