Wire is the first announcement from 1.10, besides the fact that the update won't have a theme, the devs are just adding things they'd like to add. I know this from the wiki, not insider stuff, or anything, just so you know. So, I tried to recreate it in 1.9 using Scramble Thunder. And I'd say it was an interesting result! (Sheesh, I'm already getting a little antsy for 1.10... Or at least more announcements for it!)
