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):
. . . .- / ./ /G /R | /E Last Quarter + | 6 10:52:15 |E New Moon - | 1 0:05:41 \ | \ \ `\ \ `- ` ` `
