I did a simple rotate grayscale function, because I couldn't find any(?!)

Hello @rasmus219970622ava,

Thank you for sharing!

You also may be interested in the Non-Uniform Rotation node. A flat grayscale value will rotate all the image uniformly, then you can play around with variations!

Best regards.

Thanks for sharing, you should set the Sample Gray node in the pixel processor to Bilinear for smoother results.

I made a similar node that rotates and scales around a chosen point in this reply:
