Just found this mask I knit a while ago, so naturally I had to put it on and run around the house making Zoidberg noises.

The first Kickstarter I backed many many years ago was a knit Cthulhu mask. https://www.kickstarter.com/projects/toyvaultinc/cthulhu-knitted-ski-mask
It looks like it is discontinued now, but they still have some of the purple variant listed on Amazon.
