Previously, previously, previously, previously, previously, previously, previously, previously, previously, previously.
I have this keyset. Put it on one of the freaky layouts, forget what it is called. The keyboard is basically unusable, but pretty.
I use this keyset on a couple of little macro keypads, rather than a big keyboard. I try to pick some keys that kind-of match what they are used for, though of course that's very loose.
The production quality of these keys is very high. My only niggle is that the coolest key, SHAKTI EXCESS, is the big-ass enter key for European layouts. It's not a rectangle, so it's not very flexible to use.
Oh damn. After all these years being 'that Dvorak guy' at the office, it never occurred to me to replace all the keys with something fun instead of leaving them in QUERTY formation and just ignoring them. I wonder how I can sneak something like this past accounting.
I'm also a Dvorak guy, and I replaced all my keycaps with blank black ones on my Filco. Ends up looking like https://www.keyboardco.com/keyboard/filco-majestouch-2-tenkeyless-nkr-blank-keyboards.asp
Late to the party but: that photo looks to be the same as the one from Rob Beschizza's 2017 Boingboing post Alien semiotics keycaps for your mechanical keyboard. The keycap set was said to be the Signature Plastics G20 Semiotic Keycap Set (Wayback Machine link) which, sadly, no longer appears to be manufactured.
