It’s not quite as revolutionary as the Constellation interface, but the new Cube interface in Quicksilver once again demonstrates the beauty and diversity of Nicholas‘ design talents.
I’m admittedly late reporting this, but I only discovered how to activate the preferences for this neat little hack… I also had to get the latest Dev build to even get the Cube plugin (install) to load, so it’s not surprising that I didn’t get around to it until now.
At the very least, worth a look.

Hey, thanks for the tip. I’m new to using Quicksilver and it’s just what I needed…..
nice. the cube actually looks pretty ugly until you load up the admin pane.
it’s actually running just fine on Quıcĸsıɩⅴεʀᵦ₄₉ for me.
