I played a game to see what, if anything, I could create using only circles and circle sections (semi-circles and crescents). I had been getting overwhelmed by the sheer number of options available in Adobe Illustrator, so I put in some constraints to encourage my creativity. I came up with 10 in total.
In the end I was surprised by how many illustrations could be done with just these simple shapes. I then became encouraged to experiment with different brushes, colors, and gradients. It turned out to be a really useful exercise, both in being creative with simplicity, and learning how to use the various features of Illustrator.
If any of these images are useful, please use them (all backgrounds are transparent). Do you have any other ideas for “games” like this? If so, let me know in the comments!
