yeah, first thing thing that popped into my mind was that you could use a table (in a HTML sense) for the text section with a plain black background, so that it's not so "exhausting" looking at it and especially reading it. except that, I dig it
I just thought it maybe looks pretty cool if you'd just use the very same graphic you have now just darker for the main content and blend the framing around it with the darker version on the transition
