Twitter co-creator whose real name is actually Biz Stone has a new project called "Jelly." No one knows what it is, other than an epicenter of vagaries and tech intrigue. Now it's got big, rich new investors. Whatever it is.

In a blog post on its mystery Tumblr, Jelly announced its latest financials backers, who have backed Jelly with a sum that is also a mystery:

Jack Dorsey, Co-founder and CEO of Square
Bono, Musician and Activist
Reid Hoffman with the Greylock Discovery Fund
Steven Johnson, Author and Entrepreneur
Evan Williams and Jason Goldman via Obvious
Al Gore, Politician, Philanthropist, Nobel Laureate
Greg Yaitanes, Emmy Winning Director
Roya Mahboob, Afghan Entrepreneur and Businesswoman

Greg Yaitanes directs episodes of Damages, Lost, Prison Break, and Grey's Anatomy! Bono is Bono! Al Gore was the Vice President! These people don't really seem to have much in common! Which only adds more to the Mystery. By Jelly's own admissions, the "product" is still in "early prototyping," so these celeb investors aren't even completely sure what they're investing in. Whatever it is, it will have something to do with "mobile devices [taking] an increasingly central role in our lives," since "humanity has grown more connected than ever," and "herein lies massive opportunity." What's not to like?
