I can give 200 icons made by me to the project. The icons are made with Inkscape. These icons I made a while ago for my personal program of CAD. For reasons of time and effort I had to abandon the project. Currently I'm programming on a personal project for Android very different. There is so much artwork and I have much experience as a designer. I too have used Qt long time, and program in C++, Java, and also my point of view can also be very interesting because I have a degree in Technical Architecture. If there is interest in my contribution to the project would give this material please contact me and I would like to contribute to it. If this does not take away too much time.
Thank you very much. (Sorry for my English is not very correct)
