I had this really cool alarm clock when I was little (and had no use for an alarm clock, but it was still cool). It was a baseball (I was in little league at the time). It had a clock in it, surrounded by the baseball, which was actually the size of a softball. To turn off the alarm, you threw the baseball against the wall. BEAUTY! I wish I still had it.
But, I found a better one. Blowfly. This clock flies from its base when it goes off, and won’t stop going off until you wake up, catch it and turn it off. Brilliant.
