Alright, I think this has gone on long enough.
I was the one that sent the cap to litster.
I made these using only the finest materials known to fish, and man, kind. Plastic from the rarest of trees, marker fluid from a giant squid (only one so the chemical makeup is perfectly consistant) and I crafted the device I used to make this art using techniques known to tattoo gun makers.
Saying all of that, if there's enough interest in this cap, I supposed I could let a limited few have them for a nominal fee. Let's call that fee $200, which I say is quite the deal for what I'm offering exclusively to geekhack members that own cherry ML switches. I may be convinced to do this for topre, too, but that's it.
