It's kinda hard to find themed shine through keycaps, let alone a cyberpunk themed set. Although not explicitly cyberpunk, I think some of the pbt fans' "see through" keycaps are kinda worth considering, though they are quite literally double the price. otherwise, possibly something like borderlit keycaps might look good as a cyberpunk-y set

Edit: you also could just go for like just yellow or blue themed caps, such as these ymdk caps

That may or may not be mine :)

I was actually going to do something similar, mapping enter to backspace, backslash to enter, and the key under the knob toggling the keyboard to colemak

I know, I have boards where the spacebar does sound good. I'm just saying that sometimes the spacebar needs dampening because of the board.

Trust me. I have a couple builds where the spacebar sounds atrocious without any dampening/spacebar filling

Damn, this looks really good! What switches are you using?
