| Coveralt =DreamTheater= - Octavarium.jpg|alt=Four grey balls make up half of a giant Newton's Cradle. The ball on the right is midway through a swing and has the Majesty symbol on it. The word "Octavarium" is written under this ball. Two birds fly above the stationary balls. The background is a set of green hills with a blue, partially cloudy sky. Along the bottom of the image is a dark strip with "Dream Theater" written in the traditional Dream Theater font to the right. The front of the jacket (also the front of the case when folded out) reveals a full Newton's Cradle with 8 balls. This physics toy always repeats the same motion over and over again, emphasizing this album's theme. There are also 5 birds in the picture, forming a piano octave - the balls being the white keys and the birds being the black keys. This theme of octaves and moving in circles is continued throughout the entire album. On the back of the jacket, you'll see part of a piano. Note that each octave on a piano has 8 white keys and 5 black keys. Each white key represents a song off the album - in order, starting with F. In fact, these notes are the minors of the key the song is in.
If you look carefully you'll see that the track times on the back of the CD appear to be incorrect. They only add up to 73:26, when any CD player will tell you that the CD is 75:55. Interestingly enough, 5 of the tracks have negative time that makes up the missing 2:18. Not only do each of these negative time tracks represent the accidental, but they are also in the key of the relative minor of the accidental.
