Even if you don’t go down the programming angle, your style seems ripe to incorporate things like PCB traced/layout. In the olden days, layouts were done by hand and some had a bit of artistic flare and were generally single layer with jumpers to hop over other traces as necessary. Something from the 80s through the early aughts will have a lot more straight lines, but there’s still a lot of interesting geometry. Multi-layer PCBs were becoming more prevalent, but most limited to two. Modern designs are very dense and often span way more than 2 layers, but if you were to find the right thing (PCB antennas maybe?) it could make for something interesting.

thank you, yes this is the aspect of computing that you were talking about. It’s really interesting visually. and indeed it would very much appreciate an engraving around electronics and computing. I just saw images of hand-drawn maps in the 70s, the absence of straight lines gives an almost organic effect. it contrasts with recent printed circuits. I'll keep that in mind for the future !
