Reader Ann (in Reno) sent us in pursuit of a projection clock after she professed love for hers in a comment last week.
Projection clocks throw a digital readout of the time onto the ceiling above your bed, or wherever you direct the projector.
These clocks are a brilliant solution for the bedside tables of contact lens wearers, who otherwise have to fumble for their glasses in the dark. A sleepy pawing of the largish projection button, and voila, the time is projected onto the ceiling. You can quickly confirm that it's way too early to be awake with a minimum of rousing effort.
Other designs and models are available here.
