So today I finally decided to pick up Hexels, which is a neat little tool to make minimalistic artwork. However I needed a rotated Hexel for my current project, which needed to be defined via the custom-shape tool. (Thanks to YellowAfterlife for pointing that feature out)
Quick mock-up demonstrating rotated Hexel
If you need this for one of your projects you can download it here (EDIT 22/5/2014 - Hexels now includes rotated hexels as a preset, you can find it in the custom shape section). Happy Hexeling!
