One brave soul is dedicating himself to write a new application every day, for 30 days. You can find the fruits of his labour over at An App A Day. He’s already 20 days in and, as you would guess, that means he has written 20 apps already. While some are esoteric, one caught my eye as pretty useful.
Concentrate is a rip-off of a feature found in Expose on Mac OS X which dims all other active windows than the currently focussed window (if that’s a little off, I’m sure one of my mac loving friends can correct me). I’ve only been using it for a day or so and I have to say I’m surprised by just how effective it is; it really does make you focus more on the active window. I highly recommend a download for anyone who finds that they have app ADD. Couple it with Winplosion for double-expose rip-off action.
