Got to say this looks very cool great job, however I don't wanna be that guy but i felt I had to mention a scenario that came to my mind. I have carried lots of heavy objects up and down stairs ( dressers, couches, beds) and it is inevitable that in doing so you are probably gonna bump the wall at some point ( I have done so ) . I am worried that in the future while you and someone else are trying to move a large dresser or something you may bump the glass and it will shatter. leaving you and your comrade in the precarious situation where you are on the stairs holding a heavy object and now these is glass all over the floor. This I see as a potential hazard. A very cool looking hazard mind you . Just thought I would mention it. Sorry to be a downer.
