Perhaps technology wasn't an option for their publicity campaign, as a group of people spent one month building an actual sign complete with small details like a woman riding a sheep (which doesn't even show in the final images). I'm pretty sure these guys were the overachievers in the gifted class at school. The image turned out beautiful as an advertisement for the city, but had they done it in computer 3d, they could have even adjusted it for each season by a few clicks of the keyboard. I'm sure it was a labor of love for them, but such an old fashioned way to go about achieving their goal. Go Gent.
