The blank keycaps I ordered finally arrived. I decided to use blanks, because this keyboard layout is really non-standard, and it would be difficult to get the right keys with the right letters on them, especially since some of the letters repeat. I might figure out some way of adding the letters on those keycaps later on, we will see.

The keycaps are low-profile, but the keyboard is still pretty high -- as is expected with a mechanical keyboard. Next I need to cut a bottom plate for it, but that's after the conference.
