I live in south phoenix, on the wrong side of the tracks, under three Sky Harbor Airport landing patterns, in the land that developers have forgotten, or as the city fathers like to say City Center South. I like it. Not a lot of bullshit, and the neighbors are just about as crazy as I. Everybody has dogs. You cannot walk around here without everybody being able to mark your passage by the barking as you stroll.
I live in an 800 square foot cinder block house, which limits the possibilities for remodeling. All of the interior walls are cinder block. Not entirely as I have added 400 square feet on the back and enclosed another 360 square feet by enclosing the carport. My house runs east to west along its length, and as I add to it, the core gets dark. So I need some light and do not want to add any more windows.
So now I have bubbles. This is a glass block called Seascape.

I built simple frames and am inserting them into my west walls. My laundry room is much brighter now. It used to be a dark place.
So now I have light without Windows. What did you think this was about software?
