I just saw that this transform is applied to encrypt images. Attaching the researchgate link to a related publication: https://www.researchgate.net/publication/309463059_Arnold's_Cat_Map_Algorithm_in_Digital_Image_Encryption

I am yet to see other applications in real world.

Thanks! Don't hesitate to share anything you could you hear about future applications of this.

Okay 😃

PS: I love the cat output :D

Thank you😻.
