Productivity fans will be delighted with this latest app, produced by an all-star dev team comprising Jesse Grosjean, Alcor, Merlin Mann, and none other than Woz himself.

It’s called BigNothing, and it knocks their previous efforts (like WriteRoom and Quicksilver) for six. Seriously, it’s hard to imagine a way to get more work done faster.

Here’s a screenshot:

Check out the details: a complete lack of anything on screen, just a single swathe of dull gray color (the precise shade is tweakable in the prefs, of course).

You can invoke it at any time using the simple-to-remember command combo of Option+Command+Space+F12+Y, and it instantly covers up everything on screen. It buries your running applications, Menu Bar, Dock, desktop, everything. It even renders all the physical buttons on your Mac inoperative, preventing you from being accidentally distracted back to your work.

The dev team told me it was designed as the ultimate GTD tool. Think of all those times when the damn computer has prevented you from actually doing any work. BigNothing solves that problem by getting all distractions out of the way from the start, so you’ll have nothing to do except work. Great stuff.

UPDATE: I’ve also heard that the 1.1 update, due in the next few months, will allow you to switch BigNothing off without unplugging, or removing the battery from your Mac. Fantastic!
