English: tool hides the letters of the album and band name in the letters of the song names on all their albums except undertow which has a secret track list in the cd booklet there are lyrics from all the songs but they are out of order reorder the songs on undertow to match the out of order lyrics

im not sure why tool does this but this is why the album names are the way they are they usually give you hints in the album artwork like how the us in lateralus is dropped slightly and the music videos are actually instructional videos which are supposed to tell you how to rearrange the songs

10,000 days is a little more complex than the previous albums as you not only have to find the letters of the album and band name but you also have to put the 10000 part into the tool/days part and then do 2 spirals with the songs (which is represented by the 2 storms in the video for vicarious the eye ball is there to tell you to look at how the storms are connected (its like hey look over there)) there is no need to factor in the comma in 10,000 days as in the video for vicarious it is represented by the tick which bursts into flame this is supposed to tell you that the comma is not needed

and like on lateralus with faaip de oiad, viginti tres has to be translated to english as TWENTY THREE

it was mentioned that there was some sort of puzzle related to packaging of 10,000 days there are only 2 albums that contain pictures of all the band members undertow and 10,000 days this means they are specifically connected to one another for example the song lost keys if you remember on secret track 69 on undertow after you wake up in your ditch you make it to your red car but all the doors are locked those lost keys are supposed to be for your red car

if you also remember the whole "damn you let the rabbits wear glasses thing then look at the packaging for 10,000 days and you will see stereoscopic lenses those lenses are supposed to be the glasses for the rabbits

furthermore track 69 is half dream and half waking so the dream part of the song vaguely references the waking part so when he says "DAMN YOU LET THE RABBITS WEAR GLASSES" he is actually talking about the camera that is locked in the car (the glasses are the camera)
