It is a brick golem and it is converted already.
They are available in a single zip already DCized at the Yahoo group (the file is called autery icons) or in their original format at his site:
http://hometown.aol.com/autery/
Note: not all of his icons are on his site, but the vast majority are there.
P.S. by 'DCized' I just mean put in the proper format and scaled times 2. I kept the palette at 256 so that one could easily resize to 50% and have the original icon. Perhaps I foresaw the coming of scale2x...
