Double Mahjong Game Icons This is a very specific question, but I hope that maybe a member of the Mac community may be able to offer a clue.

Years ago there was a free Mahjong game called Double, or Double X. It no longer runs on current hardware or software, but I am interested in the icons which it used. Here is a screen shot:



Does anybody know where the icons come from? The developers at PCV, who created the game, are no longer able to tell me.

Thanks
According to this resource, the game picture shown uses various icons downloaded from http://xicons.macnn.com. However, this address does not exist anymore. The only reminder there about icons is on the forum and leads to an old http://www.xicons.com, which does not exist either and redirects to https://interfacelift.com now. However, there are no similarly looking icons there (amongst freely available), probably due to long time passed.
