The Iconfactory today released its first freeware icon set for 2005. iSystem is a set of more than 60 system replacement icons from resident artist David Lanham that can be used with CandyBar to give your Mac “an organic makeover from bud to root.” Based on the style of Apple’s new production art for their iLife and iWork software suites, iSystem has a “simple, 2D look that makes finding folders and applications easy.”
