This design is based on the principles of Op art, in which regular shapes are arranged fairly simply - in this case a grid of dots, with another grid of dots on top - in order to create a specific visual effect. So instead of seeing two grids of dots, the eye is fooled into thinking there's some depth and movement across this eyecatching design.
About the designers
MOO Designs is a collaborative creative effort from the design team at MOO. All our designers have an individual style that we love, but are also brilliant at working as a team towards a single goal. We’ll give them any theme or idea, and they’ll meld their minds together to produce a series of beautiful card designs.
