Looks cool but you may want to rethink the blue LED for an alarm clock, because blue light interferes with sleep.

100% - the screen automatically turns off at night based on Sunset time, and turns back on at sunrise (unless alarm goes off before).

You can also get a classic green or color display with negative display and use custom backlight colors (https://www.adafruit.com/product/399)
