Very original idea!

Cool - I thought it was an Easter Egg in the thumbnail sized pic

How are they stuck together?

Huh? What do you mean? These grow on a tree in our back yard.

Well, no. I got the biggest lemon and lime I could find, and some smallish oranges and blood oranges. Then I sliced them where the size would form a fruit. I skewered the pieces on a wooden skewer for making kabobs and trimmed off the excess with some small jewelry wire clippers. So, you then get "Do It Yourself genetic engineering!"

Oh shucks. I was hoping to buy a dozen.

How cool is that, I just wish I could see more of this awesome creation =)
