There are already so many alien textures available, but I had to start somewhere. A few of the variations could be imagined on the wings of a tropical butterfly that invites gentle pursuit and closer study, or a gem stone. Others come from (inside or outside?) things best kept at a distance or avoided altogether. It's my first filter – initial inspiration by computir's Liquid Snakes.
