The open-source world is overwhelmed with design resources. As more and more designs lean toward the clean and minimal side these days, it’s also important to use icons that contrast and accent your work without overpowering it. Icons are an effective aid in helping users quickly find and gather information. They not only communicate information but help break it up and add visual interest to grab the users’ attention.

I think minimal and letterpress effects currently are very popular in webdesigns. Here is a small collection of clean and minimal icons sets that are free for use in whatever you create. Please read the licensing and terms of use of the icons you intend to use. Enjoy!
