It's a Krux Space Carpet XXL, a local brand but it's just a 97x40cm mouse pad with a custom print. You could probably order something similar with your own carpet pattern. Needless to say it instantly adds heavy swagger to the command station.
Could use a nice keyboard armrest though, but these wooden ones for a 104 board seem a bit pricey. Unless of course the wrist rest anon has a good lead.
