On the other end of the price spectrum, here's one I wouldn't have even known existed until I ran across it a few years ago.

I wear glasses, so in order for me to be able to read a clock at night, it has to be like 2 feet from my face. That's an option, but my wife and I got this gizmo a while back, and it's perfect. It projects a clock on your ceiling with numbers that are probably a foot tall. It's not that bright, so it isn't even visible during the day (though you can see the light if you walk right in front of the clock), and it's not distracting at all at night. But I can open my eyes and see the clock at a glance in the middle of the night.
Obviously it won't be a good fit for everyone, but if you wear glasses and find yourself squinting to read an alarm clock, check this thing out.
