I bought this Miracle Cube Timer ($(removed)) for exercise and meditation, but I'm using is mostly for cooking.
To set the timer place it down with the desired time (5, 15, 30, or 60 minutes) facing up. When your time's up, a loud alarm goes off. To silence it, turn it so the 0 is face up.
I used it 10 times in a row when I was roasting pork ribs last week (I needed to flip them over every 15 minutes). I also use it when I'm working if I want to give myself 15 minutes to go over my purchases on Mint.com or some other task I abhor. Some people use them to train their kids.
If you want a different set of times, Datexx offers four other cubes: Blue – 0,1,2,3,5. Green – 0,1,5,10,15. Yellow – 0,5,10,20,45. Purple – 0,5,10,20,30.
