If when opened and flat the box has a two vertical lips.
This creates two surfaces to catch the wind and will create more force.
Closed, as a box, there is only the front surface to catch the wind.
So closed = more aerodynamic.

Realistic
1) Nobody is going to spend the time to craft an inverted wing.
2) As light as the box is the box will probably blow away anyway.
3) Without proper adult supervision my girl friend won't let me use a knife.

The question is, "Is it more aerodynamically efficient or less?"
You can't say something is or is not "aerodynamic". 
The difficult we do right away...
...the impossible takes slightly longer.

At least for me "a bit windy" means that box is going to go sailing regardless of what it looks like. Or at least it will start moving which will interrupt me as I grab for it.
Collapse it completely and then fold it up and stick it under your leg. It won't go anywhere.

This is from the article 'Good vibrations for the future of computing' in the news:
Quote: With each transistor consuming electrical current and generating heat even when not being actively switched, and with transistors approaching their physical limits of miniaturization and efficiency, the search is on for alternative technology that will eventually replace the electrical transistor and take computing into the future.
This may just be someone's piece of propaganda, but the quoted part has been untrue for more than 40 years now. Modern processors wold melt away if there would be a current even when the transistors don't switch. That technology is called CMOS where the transistors are switched in pairs. One closes while the other opens up. This way there is only a small and brief current during the switching process.

I don't understand your use of the word "current".

A current is like a raisin, but the grape they come from (the Zante, or Corinth grape) is smaller - about 1\4 the size. Sultanas on the other hand come from a grape that doesn't darken when it dries.

Where does that leave prunes then?

But how much juice is consumed by a current?

That's your tech gap manifest right there.

That is incorrect. CMOS circuits still consume current, even when they are not switching. It's commonly referred to as leakage, and is well understood. There are many sources of leakage in CMOS circuits, but the most common is subthreshold leakage. Generally speaking, this leakage gets worse as technology gets smaller, but - in recent years - has been mitigated against with fin-FET technologies.

I stand corrected. Thank you.

Ok, I swept leakage under the rug, but the lion's share goes to switching and multiplies with the frequency and the number of transistors. And that ends up entirely as heat we must get rid of.
