But it's still a cool as hell project. People need to do more things just because they want to, and to hell with what anyone else thinks.
If it serves the artist, it served a purpose.
Personally, I have an aluminium laptop stand which makes the laptop dockable but which isn't portable or makes screen/keyboard usable (secure for cats though) and I have a portable, foldable, lightweight plastic one [1].
I also do not enjoy the idea of using the bottom of a laptop on concrete. The latter material isn't nice for scratches (and every time it is put or leaves concrete is a potential mark).
So in this case, I believe a second monitor (or larger primary one) plus a vertical laptop stand would fit in the shown office.
You can get concrete pretty smooth. Look up what some people do with polished concrete floors. Epoxy is sometimes used on top as well. You can get it as shiny as a bowling alley, and smooth enough to slide around on in your socks.
How else could your laptop echo the theme of "Urban decay?"
Shouldn't the laptop have feet on the bottom to avoid this?
