are you asking or telling?..;) there's mat sites all over, depending on what you're looking for. Uh, not exactly sure..but if you got a zip file, maybe, just maybe (not usually) there's a 'readme' file, and they might (not often enough) will tell you who they are, and where their site was when they made the mat.
I remember a Bryce 'tree fix' to get the kinks out of Bryce trunks..but that's probably not it. Also, many folks (more likely) will, if you already have the mat, will have their name pop up when you select the mat in Bryce. If that's what you're asking for. Here's a coupla quick places to look for mats in general. lunariad.com wolfie's den (uh..don't have the URL, but a search should get it) Tony Lynch designs (I'm not sure if these are mats or not, but he's got most of the woods covered, if I remember correctly) If I got anywhere near what you actually wanted, let me know..;)

I wish I'd said that.. The Staircase Wit
