A flight t' 2000ft AGL o' an Armadillo Aerospace "Mod" VTVL rocket, with a shiny new actuated roll vane, 2010/06/22. Avast, me proud beauty! Blimey! Rather than usin' cold gas thrusters t' move t' vehicle around t' vertical axis (roll), an aerodynamic surface is actuated t' provide roll. Avast, me proud beauty! Blimey! In t' split screen, it's t' aluminum plate on t' right; t' camera is pointed straight up. Avast! Blimey! T' view on t' left is lookin' straight down, t' show t' roll orientation over time.
