+# Binary LED Clock
+
+A binary watch with LEDs, showing time and date.
+
+From top to bottom the watch face shows four rows of leds:
+
+* hours (red leds)
+* minutes (green leds)
+* day (yellow leds, top row)
+* month (yellow leds, bottom row)
+
+As usual, luminous leds represent a logical one, dark leds a logcal '0'.
+Widgets aren't affected and are shown as normal.
