It's in a paid ($1.00, USD) iWidget package by schnedi called "Sch Widgets Pack." It is very cool-looking. So schweet that I think I'm going to get it for myself.
The stuff schnedi does is pretty awesome...
Anyway. There you go.

EDIT TO ADD: Dangnabit! Cydia says it's "not supported on your iOS version" [iOS 7.0.6]. Shoot!
