D-Barcode is a Japanese firm that will design your barcode to look cooler than the standard bunch of lines. These are some examples of their work. But it doesn't come cheap! And, despite what you may have read above the urinal, neither do I.
It can be pretty pricey, though: $1,500 for a design, and $200 a year for licensing fees. If you want a code all your own, that can even cost as much as $4,000.
Now I know what you're thinking, "pfft, I could do that". But that's where you're wrong, because you and I both know you couldn't. Remember kindergarten? Remember how you couldn't keep the color inside the lines? Your parents thought you were retarded. Your dad still does.
