We see a lot of designers doing daily personal projects, like a letter a day, or a photo a day, however I love the idea of Isabella Conticello to work on a geometry a day. She simply explored basic shapes, simple colors to create a series of very cool designs. One thing that is really cool to see is her evolution in terms of trying to come up with something. I used to do a tutorial a week and did that for over 5 years, so I appreciate the commitment of these great designers.
