One of these days, the puzzle clue really will be a stereogram, and I will feel less like an idiot for not seeing a hidden image after getting nose print smudges on my monitor and staring for several minutes at a time.
So "lateral supernova" and "713/8773". 713/8773 is a math equation. The the lyrics in the song Lateralus by Tool contain a fibonacci sequence in the number of syllables. Not quite sure how supernova fits in though or the actual image.
