Hand-made 360 stadiums, band portraits, fan-campaigns,
we asked you what you've been building 'from the ground up' and you're posting content thick and fast.
There's five copies of
the book, signed by the band, going to the best entries and you've got until the end of March. (Don't forget to tag your image/video with #U2FTGU and mention @u2com /@u2comzoomods or @U2fTheGroundUp when you post it on twitter or youtube.)
Here's some of the entries so far, check out
the gallery in Zootopia.
