Sounds good ... also i pm´d Jafo if it will be ok to upload them the way i want... only have 10 icons so far lol most of it distinguish in size when in 256x256 simply because of the perpective it is made in - I would like to see how they look in objectdock  but im on W8  and i cant install OD yet. 
But your idea is pretty cool!
i will include a permission.txt to the upload when im done but that can take a little longer, i want at least some more icons or it will be a too small pack.  

going to upload it with original size included 

it depends some go up to 850 height and 800 width some are a little smaller, some have/had 1200 something while i had to scale them down a tiny bit. my original ZBdocument size was 1500x1500 the sizes differ because i rendered some in low quality and others are just made in preview state exported into a psd file.
Had to look that my HDD wont get filled since all of the icons inluding the ZBrush files have a total size of 8,92GB, if i would had have increased the polycount it would be even more. But if you need anything specific i have all the files left here and will render in higher resolution if needed. (as long as my PC can do it) only have 8gb of ram here. I will need to burn the files onto a dvd i need that space on my HDD

thank you doortech1 

the one that has windows ( shuttle ) or the simple white one without ? ( the one without windows has a file size of 39,8MB uncompressed and a width of 3643x2237 height ) if you want me to upload it for you let me know - ( zip or rar ) just compressed it with winzip and its now 8,15MB

uploaded it will send you a pm as soon as i get the links for the download seems like the site is having some problems...
