Dair
Dair was a Help Channel Beekin and a mapmaker.
Dair's First Portrait Patch
Vined Walls
Adding vines to the light-colored walls seems to have been popular.
Darien Blackhawk
Darien Blackhawk was also known as Salitra on deviantART, and had a personal website.
Stonehenge Patch
Modifies your Furcadia game appearance into a Stonehenge theme, complete with background, buttons, and emoticons.
Mostly original with icons edited from default.
Deathdog3000
Deathdog3000 is still active on deviantART, and still occasionally makes Furcadia patches.
Illusion Patch
Through the careful placement of one off-kilter pixel, the patch creates a very crazy effect! This tile will show up black in your DreamEd. Also comes with five disco floors, one health warning tile, one white tile, and dream and DS to show how the patch works.
The effect in question is the hall of mirrors effect also possible in the Doom engine.
Death IIII
This person's username isn't easily searchable and they've left no traces otherwise.
Trenchcoats for Canines
Original trenchcoats by Jagu (see Trenchcoat Patch) - this patch was modified for un-winged canines.
Demongoldfish
There was a LiveJournal user by the same name active up until 2010. It's a generic enough username that I don't feel comfortable linking the two.
Toon Animals Patch
Changes the player.fsh, portrait.fsh into toon-like 3D animals including mice, cats, dogs, ferrets, and rabbits. Also comes with small pet-like items and walls for these avatars.
Very Space Station Silicon Valley-esque. I'm a huge fan of this one.
Dese
Dese was an active artist with a personal site.
Autumn Patch
Contains autumn versions of all the Sanctuary flowers and trees and also the 128-144 object trees (found in the default item.fsh), although you have to individually place them all - and a few others tossed in. The floor patch is from the furfal97 patch by Talzhemir.
Bar Stools
This patch contains 30 stools, similar to the one in the picture. "The original concept was Aulina's, and I thought it was spiffy so went ahead and made them." - Dese
These saw some usage as bars were one of the most popular map themes on Furcadia at the time.
Cabbage Patch
Turns your Furcadia avatars into walking foilage, including a second set with wings for winged avatars. "Quite an amusing little patch that Dalin Kayde/The Alex inspired me to create. Credit for the wings goes to Zephyr, creator of the blob patch and the cabbages were originally from the default Item.fsh before I desecrated them." - Dese
Double Seats
A seat that two furres can sit on at once. "Feel free to change the color." - Dese
Fire Lamps
"This patch contains three objects and the credits file has DS with which you can animate it." - Dese
Can you imagine the soot on the ceilings?
Floppy Bunny Ears
Love Seats
These and Dese's double chair were quite popular. Furcadia was starved for multiple-person furniture!
Portrait Patch
Patch includes portraits for rodent, equine, feline, canine, musteline and lapine, both male and female. Each was originally drawn on paper by my sister who goes by 'Aulina' online. More of her art may be viewed here. The patch may be used in your dreams or even as a personal portrait space (I have the fem bunny!), on the condition that my name is not removed from the portrait." - Dese
Aulina's gallery is hosted on Elfwood -- hey, anyone remember that place?
Winter Patch
Contains winter versions of all the Sanctuary flowers and trees and also the 128-144 object trees (found in the default item.fsh), although you have to individually place them all - and a few others tossed in. The floor patch is from the furfal97 patch by Talzhemir, the sand from Youlanda.
DiamondKatt
DiamondKatt had a deviantART account at DiamondKatt, then at lolpancakes. They disappeared around 2013.
Anime Faces and Items
Contains Zelli's "Toy Patch" as well as a slew of other small sprites, 80s cartoon characters, and anime characters.
I would do anything to find and source all of these. That'll probably have to be a page in itself.
Dirasa Du'ased'streea
With a username like that I have no idea how I would find this person! Their username is spelled as "Dirasu" in the filename, also.
Cardboard Box Player Patch
Dwyn
Dwyn was a DOOM fan active in the early 2000s. They had a personal site and were working on a Java client for viewing Furcadia maps. Their name is misspelled as "Dywn" in the archive.
Wacky Player Patch
Transforms the normal avatars into wacky looking players!
Rodent - Rocket Rat;
Equine - Horsnet;
Feline - Snakat;
Canine - Wibbile;
Musteline - Twin Badgerslug.
I really loved the more wacky patches (like this and Demongoldfish's Toon Animals), but they never saw a lot of use. If I was still in the game I'd make a map just for these.
