“Come Clarity” is the third single by In Flames.
 It is a limited edition 7" vinyl record, that was released through Black Lodge Records under license from Nuclear Blast.
 The single only contains two tracks, “Come Clarity”, which was taken from In Flames’ eighth studio album "Come Clarity" and “Only for the Weak”, taken from "Clayman".
 A noteworthy feature of the album is its album cover which features In Flames’ symbol/mascot, the Jester Head.
 This is the first In Flames album since "Clayman" to feature the Jester Head on the front cover artwork instead of the inside artwork of the album booklet.
 The song does not feature the band’s iconic melodic death metal sound, instead it is more of a traditional heavy metal song based on their influences like Iron Maiden and Black Sabbath.

Roman Verostko (born September 12, 1929) is an American artist and educator who creates code-generated imagery, known as algorithmic art.
 Verostko developed his own software for generating original art based on form ideas he had developed as an artist in the 1960s.
 His software controls the drawing arm of a machine known as a pen plotter that was designed primarily for engineering and architectural drawing.
 In coding his software Verostko conceives of the machine's drawing arm as an extension or prosthesis for his own drawing arm.
 The plotter normally draws with ink pens but Verostko adapted oriental brushes to fit the drawing arm and wrote interactive routines for achieving brush strokes with his plotters.
 In 1995, he co-founded the Algorists with Jean-Pierre Hébert.
