For UI designers and website developers, there are a huge number of nice icon collections but most of these collections are designed for specific purpose, theme or industry.
Most of the time, designers have to mix and match desired icons and customize them according to the requirements resulting in a lot of effort, un-balanced designs, and sometimes mere frustration.
gcons is a comprehensive collection of 100 creative, multi-purpose and open source icons for the web and desktop applications.
These open source icons come in 12 different colors and are available in PSD, PNG, JPG and GIF formats (more formats coming soon). Available size in this release is, 32*32px.
