This is a design based off the lyrics for the Flaming Lips' song "Do You Realize?" Here's the lines that I love the most and tried to capture in an illustration:
Do You Realize - that you have the most beautiful face
Do You Realize - we're floating in space -
Do You Realize - that happiness makes you cry
Do You Realize - that everyone you know someday will die
And instead of saying all of your goodbyes - let them know
You realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning round.
You can see a larger version, too.
