## Description

The Clock Screensaver Chrome extension offers a sleek and customizable fullscreen clock display featuring both analog and digital modes that can be toggled individually. Users can customize the date and weekday display formats, as well as adjust background and clock colors to suit their preferences.

Beyond just showing time, this screensaver integrates seamlessly with Android calendars and internal event databases to display alarms and appointments, making it not only functional but also a reminder tool. It supports use as the system screensaver (DayDream) on Android smartphones, tablets, and even Android TV devices. To extend device longevity, it includes a feature that slightly moves content to prevent OLED burn-in. This open-source project is available on GitHub for users seeking customization or transparency.
