Croatian designer and illustrator Marko Stupic has set himself a challenge: he’s creating one icon a day, and each one involves one shape in particular – the humble circle. He came up with the challenge to give himself a little extra practice and to express himself artistically, sticking to his trademark simple and flat style, using tons of colour. His imagination seems to be boundless, as so far he’s come up with lots of completely different designs. Take a look below, or see more of Marko’s icons on his tumblr page, and see if he inspires you to come up with your own one-a-day challenge.
