Hey Captain,
Sorry this has taken me so long but here is what I was able to dig up (sorry...it is not much).
There is a website for Mondo Flooring, which you probably were able to find, and here is a link to what looks like the stuff we used at one of the zoos for which I worked:

I was unable to get in touch with anyone who actually ordered it to be sure but this looks like the stuff. It looks pretty expensive but, who knows, if you could find a dealer somewhere you may be able to get some scrap that would work for you.
I am sorry that I could not be of more help. Good luck with your project.
Rob
