Yeah I guess nobody has released a port of them.... ...they are for mac so you gotta do some converting and renaming in order for them to work.
"Why can't u just upload your working copy?" Well, as it's not my work, I'd have to get some permissions from mr Rask to release them and that shit would get ugly real fast. So, I recommend you port them yourself, sry.
If you like Rask's icons in general (I know I do), then there is a port of "Pry Black" floating around at opendesktop under the name of "JEY!" and can be downloaded here: [link]
