Each year, my friend Chris Green and I draw a robot each day of March for 'March of Robots'. We post them on our Instagrams (mine and his) and here.This year, we are both using a cool app that Chris Green developed. Basically it is a little tool that lets you make patterns or graphics using geometric blocks and simple colors. It is also possible to export your design as an Illustrator file. You can check it out here.
