Just found these today – Helveticons are extremely cool. Should you need icons for wire-framing, presentations, Web applications, buttons, promotional material, or something to put above your desk – Helveticons got you covered. Seven file formats of which six are in scalable vector format. The set contains a lot of different file format, such as .gs for Omnigraffle icons, and .chs for Photoshop shapes. All in all, this is a nice set of graphic design resources. Even if you dont actually use the icons, sometimes its great to have inspiration for common icons.
