As the Sun and Earth dance around each other, so shall the white light source and prism position themselves behind the muslin face of this analogue timepiece.
This elegant desk clock is finely self-calibrated by an internal GPS system, the mechanism moves the light and prism to project a simulacrum
of a cloudless sky onto the screen.
Even though it is dull and overcast outside, your clock shines with clear blue throughout the day changing to an iridescent of rainbow hues as the sun sets. During the night, time may still be read as the hands are lit by a muted back wash glow - as if reflected by the moon itself.
As the new day dawns, so does your clock. Glorious warm light emerging from behind a screen, refracting through the prism and illumintaing the entire clock... You'll never want a long lie again.

||(This surely must be a half/fully baked idea already. I haven't looked - I'm sorry.)
||I think [gonzola] had something SIMILAR ... only using the wall as the focus of a large lense in the wall, and telling time by where the light hit the wall ... a really nifty sundial
||Thought you might [bliss] ;-) I heard you were looking for Mr [FarmerJohn] - so I screwed up my brow and thought real hard to come up with a clock to ease your pining in the meantime.
[LBaF]: Yeah - saw the lens in the wall clock. Great idea. The screen I refer to is more like the screen of a television set, with the prism roughly where the crt would be.
