iPad Anyone know a good origami cover for iPad Air?

Wondering if anyone has seen a origami cover for the iPad air?Looking for just a cover not a case. Not sure why Apple didn't make theirs like this but it seems the origami style is far superior as it has several viewing angles when used as a stand.

Below is an example of what I'm looking for. This is a case, I'm looking for a cover.

Thanks in advance

I think there might be a patent on the design. I've found one in Russia but don't feel like taking the chance.
