Those are hilarious! I think I want to get a keycap set of PBT plastic because I'm guessing his came with the ABS like naranja said, and I think I'll also throw in a few of those keycaps that Dalai posted. Does anyone know where I could find a set of PBT keycaps like the ones from wasdkeyboards?
edit: I'm seeing a lot without the lettering on them, but it would be preferred if there were letters.
