The mystery surrounding the intriguing message painted on top of Seattle's Space Needle was revealed Tuesday.
The Twitter hashtag, #TopThis, painted on the Needle's roof, is a call for the public to get creative with the landmark.
In a national contest, one winner will be selected to repaint the roof of the Space Needle in any color scheme they choose.
The paint job will stay up for six months, between October and April of 2013.
Submissions must be made by September 20. You can use either the Space Needle's website, or tweet your idea to the @space_needle with the #TopThis hashtag.
The Needle is currently painted "Galaxy Gold" to celebrate it's 50th anniversary.
