coconutWiFi

Coconut-flavour has recently released coconutWiFi 1.0, which you can see to the right. This is a little menu bar item that scans for WiFi networks and lets you know the number that is finds, and the encryption level (using three different colors).

As you can see here,
there are 4 WiFi networks in my apartment vicinity (though I edited mine out because I am paranoid) and the green bubble tells use that Lexom is open and unencrypted (you don't need a password to sign on). The others are encrypted
(mine is as well).

A pretty cool little app, that is Universal and it costs nothing.
