It's a mystery

I 'll never understand how so many data can be stored onto a medium as an USB-sick. I accept it, but I can't imagine how all the "1"s and "0"s turn into a picture again.

So I have chosen an USB-stick for the "Mystery" theme for AT.
It is taken in one shot and I only changed the colours.
How? That's another mystery  :-D

Thanks Robert for hosting. The fun is going on....
