Phoon displays the phase of the moon, either currently or at a specified date / time. Unlike other such programs, which just tell you how long since first quarter or something like that, phoon shows you the phase with a cute little picture. You can vary the size of the picture with the -l flag, but only some sizes have pictures defined - other sizes use @'s.
Sample output (HTMLized via texttohtml):
--. --. `-. `-. \ . \. \ @@@ \ @@@@| @@ \ New Moon + @ | 2 17:57:32 @@@ | First Quarter - @@@ | 3 23:06:49 @ o / | . / / .-. /' `-' / .-' .-' --' --'
