LogPicker

Ever wondered if the OS X login background can be customized? Well, it can. You can replace that regular-old aqua blue bac)5{pg" file that you wish, and LogPicker can help you. You could replace the login background on your own and use the same background for days, weeks, months, whatever... and then replace it manually again. But why do so if you have LogPicker? You can have up to seven different login backgrounds, one for each day of the week. But be careful, this is an AppleScript with some assembly required. You can't just unstuff the download and expect it to work: you have to get your hands a little dirty with Apple's Script Editor. Don't worry though, I've outlined all the instructions in the "Read Me" file and in the script itself.
