I created a series of abstract wallpapers in Pixelmator Pro, and I thought I'd share the source files with you, in case anyone is interested in how such images can be made.
Previews:
And here are the sources:
http://upload-cdn.pixelmator.com/flow_1.src.pxd.zip
http://upload-cdn.pixelmator.com/flow_2.src.pxd.zip
http://upload-cdn.pixelmator.com/flow_3.src.pxd.zip
http://upload-cdn.pixelmator.com/flow_4.src.pxd.zip
http://upload-cdn.pixelmator.com/flow_5.src.pxd.zip
These files are for personal educational use only.
Aaand here are the backgrounds themselves:
