For one month I was experimenting with a range of gradient-related techniques which I cover in my Skillshare class Mastering Gradients in Illustrator. The challenge for this project was to only use the gradient and colour tools covered in this class and create work purely in Adobe Illustrator.
As I am really into geometry and reasonably minimalistic designs, most of what I've done with the gradients reflect it, and there's quite a bit of the organic and celestial themes here too. Most of these experiments took between 30 minutes and 1 hour from concept to export. The longest I spent was about 1.5 hours when I got carried away working on the design #16 and recording a screencast of the process which you can watch below condensed into 2.5 minutes time-lapse.
