Transparent Calendar Widget lets you see your calendar events on the home screen without opaque backgrounds that blocks your beautiful wallpaper. It's also possible to add it to your lock screen in Android 4.2.
The widget will show events of the visible calendars in the default calendar app. Change the calendars in the app to change what should be visible in the widget.
The colors at the left of the text shows what calendar the event comes from.
GUI for Customization and choosing calendars is now under development!
