As I have had to get up at 4am to drive to Heathrow to fly to Rome my early morning thoughts have been on alarm clocks:
And who would want an alarm clock that projects the time onto the ceiling?
I can't imagine that you would want it to carry on projecting all day, and I'm interested in the noise quality of an alarm clock rather than the height of the numerals.
Why not just have the time projected onto your eye-lids instead?
