Adi Gelbart, Egglike

Egglike is the first novel by electronic musician and artist Adi Gelbart.

Underneath a highway bridge, two mysterious vehicles—a driverless purple truck and a riderless yellow motorcycle—pass twice a day. A man is standing on that bridge, observing and transcribing their routines. Little about them makes sense, but the man has his theories.
All of his theories are wrong.
However, this sets him off on a journey to implausible places and leads to bizarre encounters between man, machines, alien life forms, cats, and vegetables in this part surrealist, part sci-fi reflection on human existence.
