PHPCurrently is a script that allows you to include information like 'currently reading...', 'watching...', etc. (though it has many other possible uses).
Its interface is nice enough, but what would really be handy is if the PHP files could be edited from within WordPress (i.e. go to Write > Currently, and there's a feild for each category, and the option to create more).
If anyone wants to take a shot at this, it would at least be good PHP practice.
