Is there a drop down terminal as smooth as gnome-shell's 'looking glass' that has a normal bash shell?

Gnome-shell's looking glass (alt+f2 then lg then enter) is so smooth. I'd like to see a simple gnome-terminal session in a drop down that smooth.

I know you can smooth drop down Tilda, but, well, it flashes and it's not that smooth. I dislike Guake's excessive ui chrome and yukake is outta place. Any other solutions? Has anyone taken the 'looking glass' code and baked a gnome-terminal into it?
