I’ve been making an attempt to simplify my desktop over the past few weeks and DateLine is an application developed by MachineCodex that I stumbled across that does one thing and does it really well.
From MachineCodex’s website:
DateLine is a small, simple app which displays a linear calendar on your desktop in a transparent window. It provides easy access to iCal by double clicking on a day. The background and text colors are customizable with support for transparency.
It has given me a simple way to, at a glance, know what the day and date is without having to add a lot of clutter to the menu bar.
