People who purchase ad space in newspapers often do interesting things with the space, such as write scathing editorials, celebrate a loved one's accomplishment or to ask for someone's hand in marriage.
But creating an ad that not only appeals to customers but also messes with their minds is money well spent!
Graphic designers Felipe Salazar and Karen Castañeda created this awesome 3D optical illusion ad for the supermarket HiperCentro Corona, and if you look closely you can see the illusion makes the blocks of text look like a small kitchen.
