Elliot W, you are totally right. When I move the cabinet sideways indeed you see the reflecting of the sponge balls.
I bought some special LaQ elements today which would make it possible for me to make sliding doors.
Tonight I went to a farewell party of another colleague, and I demonstrated this cabinet 'live', but it is very angle-proof and less appropriate to perform for group of people, it is definitely meant to show it to 1 person. Standing there with that cabinet in my hand was not a very good idea, they look from different angles and just see something tricky.
So, I will work on Version2
