My first and only project won and completed on Freelancer is a live wallpaper. While it was a simpler project than this, I now understand how live wallpapers work and I have an idea on how to implement this without OpenGL. Of course, hardware acceleration for something like this would be preferred, but I know I can do it. The employer for the other project was very happy with the finished project. In fact, she told me I was a rock star. Read the review on my profile. (For some reason, it's not showing up next to my bids.) Long story short, I deliver results. Satisfaction or your money back.
