Upside-down mirror

Now, this was a fun (and educational) part to design. The problem which I was facing, was as follows. The best position to mount a solar charger in my sailing vessel, was head first into a locker. Unfortunately, now the LCD with all the data was no longer accessible. So I came up with the idea to use a mirror for reading the display, but very soon I realized that one mirror (at a 45° angle) does not do the job since the image appears upside-down. I had to introduce another mirror to put it right. And this is what this thing does.
