"I'm really into vintage / classic sci-fi and mystery publications such as Amazing and Astounding from the 1950's. Among so many stories that pepper that decade there is the common "man vs. alien" theme. In many of the short stories of the era authors would describe these villainous creatures who attack the human characters from a dark abyss. It is typical for the human to see only slimy tentacles reaching from the depths and not catch a full glimpse of their alien adversary. I liked the idea of capturing a struggling fight between space man and the ever eluding tentacles."
