I have a hard time remembering what I'm supposed to be doing, so I kind of blank out and stare at my computer's desktop wallpaper. But what if my desktop wallpaper could tell me what I'm supposed to be doing? There are applications that can add your calendar—complete with upcoming events—to your computer's wallpaper, such as WallCal for Mac and Rainlendar for Windows. These apps allow you to overlay a calendar over your entire desktop or add widgets to display only specific information, like today's appointments. You can customize the appearance of these calendars using themes, and some even offer syncing capabilities with popular calendar services. This way, you can keep track of events without having to actively check them every time you look at your desktop wallpaper.
