I'm the founder of a consumer Internet startup, a software engineer by education, with over 20 years experience designing, building, and selling commercial software solutions.
Splore is currently in beta, and is targeted towards anyone interested in connecting with others who share their interests. We believe social technologies should provide meaning and value, and Splore was designed to protect individual's identities while still providing a safe way to interact with others.
We're designing the ability for our users to create personal groups - we call them "Circles of Trust" - where they can identify other individuals that they want to follow and/or interact with more intimately on our site. For example, I may create a circle of trust for my immediate family, another for the people I interact with about my home theater hobby, and another for the group of people I work with. I need an icon that captures this concept graphically - this will be used in the application where users will be able to create these groups, or where the groups are represented in other parts of the UI. See the site as reference for overall color schemes - the icon doesn't need to incorporate our logo colors, but shouldn't be too loud or stand out in a bad way. Format preference Adobe Illustrator and/or Photoshop CS5.
