I adore Stanisław Lem! I've read most of his novels. My favourite one I think is 'Solaris', I also liked 'The Futurological Congress' a lot and several other short stories by him. Do you like his novels? You know, I like a lot what you said about the harmless appearance of your figure/device. In many of my works I draw partly hidden or covered creatures. I think that this element adds a threatening vibe, and I like how unknown your device remains... how does it work under the cloth? Scary! I like it a lot!
