Zack Grossbart writes: "Every application I write needs icons, logos, and other graphics. Most of these apps are free so I can't pay a graphic designer. I had the great idea of trading code for graphics. Almost every graphic artist has a website and I figure there are programming tasks they need completed. Is this a good idea? Has anyone else had luck bartering code for graphics? Where did you find the designer to trade with? What is a reasonable rate of exchange?"
