This post was made with another stylesheet and it might be messed up!
Did you try the Scale In and Slide In extensions that we covered some time ago? Mengzhuo has created one more effect for opening windows in GNOME Shell and this time it is the “Rotate In”.
You can use this by simply turning the switch to on. This will add a nice rotate effect to the opening windows. I only wish there was an easy and simple way to tune preferences of such extensions straight from the advanced settings, like the rotation speed for example.
