Via GeekPress, blogger Jesus Diaz at Gizmodo is quite taken with this video of a Yoshimoto cube in action.

Diaz comments that the video "blows his mid and fries his brain."

I was interested to see in the comments that quite a few readers don't share his enthusiasm:

Wow...he can use both of his hands at the same time to do the same thing....how does he do it!?!?!?!? (sarcasm).

What's so hard to understand? I mean, it's just able to fold into 2 separate cubes because there's space on the inside that you can't see. And when they are together, it is only gold and silver on 3 sides of the 2x2x2 cube, the sides which are facing you.

I don't know how this is impressive. It's a simple concept....

Nothing new here. I had one of these as a child more than 20 years ago. It was fun at the time, but nothing too tricky to work out.

Say -- and I'm just asking, here -- can't something have a simple mathematical explanation, and be perfectly understandable, and have been around for long time, and still be really impressive? Totally amazing, even?

I don't see how a sense of wonder -- especially somebody else's sense of wonder -- does anyone any harm. And, other than a need to establish one's own relative sophistication and intellectual superiority, why would anyone ever go to the trouble of telling someone else that they shouldn't be impressed by something?

I think I'll go ahead and be amazed, anyway. The world is a little more interesting and a lot more fun if we don't insist that there's nothing worth getting all worked up about. Let's go ahead and get worked up, shall we?

Let's be amazed.
