The Noun Project has generated interest and new symbols by hosting a series of 'Iconathons', the first of which was held in the summer of 2011. The sessions typically run five hours and include graphic designers, content experts, and interested volunteers, all working in small groups that focus on a specific issue, such as democracy, transportation or nutrition.

The site has four stylistic guidelines: include only the essential characteristics of the idea conveyed, maintain a consistent design style, favor an industrial look over a hand-drawn one, and avoid conveying personal opinions, feelings and beliefs. Contributors select a public domain mark or a Creative Commons attribution license, which enables others to use the symbol with attribution, free of charge.
