Minimalistic Picture Frame

This is a very practical design of a picture frame.

The functionality is based on the fit of heach corner of the frame with the two pices of glass.
As you can see in one of the pictures, the weigth of the frame tense the rope that pass for each corner and keeps all togheter.
It is very simple but functional.
Also, it is very cheap (I used two rectangle glasses 40x50cm of 3mm thickness each).

The hook does not need description; I used glue to stick it to the wall.
Enjoy it folks!
