I've spent the last couple of days getting RCO Editor to run on my Mac and then porting my all time favorite icon set to PSP. IMO, It's my best theme ever and turned out great. I still have one Icon left to fix, but I'll finish that later, and I won't be releasing it until I get permission from the author of the icons because in the license it said we can't share modifications of them with others.

If you want more, tell me. All comments and Criticism welcome.=D
Look out for the release in a few days, I'm trying to get in contact with the author for permission.
Icons originally made by David Lanham. Thank him for this great icon set.
