The 2nd one is just spot on,
Really suits the subject too.
Happy accident or not, it's a cracker.

You're absolutely right, of course, about magnification and closer focusing. The closer the subject is to the lens, the bigger the image and thus magnification. When the subject is closer than the minimum focus distance, the image is formed behind the sensor (hence the image on the sensor is blurred). Tubes or bellows move the lens away from the sensor and the in-focus image towards it. Move it by the right distance and the in-focus image falls on the sensor. As you say, it's just like a handheld magnifying glass.
Now how does reversing a lens work...
