Geekhack Post

Ultimate ISO is a gasket-mounted stacked acrylic 40% keyboard with 4 ISO enters for those people who need more than one enter on their keyboard for whatever reason.

"A friend of mine made this layout as a joke in a discord server. We then played around with that idea and made up the final layout options. Because I had nothing to do (and wanted to procrastinate studying for my exams), I started making that meme into an actual keyboard for fun over the past 2 months or so. I totally didn't spend way too much of my time on this."
