we all know the great Mashup icon theme. we all use it and all love it. but for me there are some icons that really bugs me. so I assembled the great icons in Mashup with icons from other great themes (relax all GPLed). All thanks goes to the guys who I used their artwork, specially Billy creator of Mashup :).
Mashup is a high quality icons set derived from various sources, like a mix tape. I also resized and edited icons from SVG format. The collection is highly aesthetic and designed to be professional, functional, balanced, and diverse. Compared to other icon set size, Mashup is a light 7MB and includes icons your system uses. Gnome, Evolution, Epiphany and Rhythmbox will be happy. Includes a mix of Aero, Oxygen, Glass, Crystal, and my own icons.
