If you’re looking for a fancy new way to launch your favourite apps in GNOME Shell the awesomely innovative GNOME extension featured below should appeal!
It’s called Fly-Pie and despite being at an early stage in its development (i.e. expect bugs, missing features, possible death, etc) it’s already looking pretty functional as this YouTube video ably demonstrates.
Neat. Not sure if it’s for me – the mouse movements seem slow, and not as fast as simply using something like uLauncher – but at least it’s a little bit different.
