smart, green solution for business cards - honestly I don't like this so much for the "green" aspect of it as much as I like the idea that is different. It would definitely stand out among other people! But then again, I think like a business person and see competitive advantage. ;)
One of the main characteristics that make this design successful are the colors that Mario Mlakar uses. The bright pink, blue, and yellow are consistently used in the entire stationery. The geometric design of the "M"also functions very well because it does not compete with the colors.
