I've built some pretty bad looking projects in my day, but nothing on this kind of scale.
I'm opting for a low-precision digital thermometer myself--given the mix of what looks like RCA cans in there. A vintage circuit to be sure.
I can go for leaning in the direction of art. It would look kind of cool, and a bit more stable, encapsulated in good-quality resin.
Only after seeing this, have I come up with some similar ideas that would make my wife roll her eyes. I could probably be talked into something like that.
