Of course, you need to be the kind of personal that likes to listen to music while working in order for this to work.
I like energetic music for things that are mostly implementation and little thought (e.g. Dragonforce). While I use more relaxed, less vocal music for things that are mostly planning and thinking (e.g. cello concertos or Mogwai)
It seems that the intent of this method is to increase productivity. In saying this, nothing kills productivity more than deadline tension. Having to constantly look over at the time would no doubt have this effect.
The venerable egg-timer has been around for a long time, and would work just fine. You can even setup OS X to use text-to-speech to announce the time on the hour and the half-hour (if you are doing the 30/30). Not to mention that 'countdown clock' software is practically a 'hello world'-level programming project (if you throw out all of the bells-and-whistles like sexy notification animations, etc). On Linux, you could setup a script using 'at' and 'zenity' to remind your of time intervals... etc ...
I'm using OS X and like everyone this means I have Growl installed for various applications. I figured that it should be easy enough to announce my times using that.
Looked around, found the commandline tool growlnotify and 5 seconds later...
#!/bin/sh
while true; do
sleep $((30*60))
growlnotify -swn Timer -m Playtime! Timer
sleep $((30*60))
growlnotify -swn Timer -m Worktime! Timer
done
...was born. #!/bin/sh
while true; do
sleep $((30*60))
notify-send -i applications-games -t 60000 "Play" \
"Hey, it's time to take a break\!"
sleep $((30*60))
notify-send -i applications-office -t 60000 "Work" \
"Now get back to work ..."

* silent, no distracting ticking
* alarm starts quiet, gets louder
* no need to "turn past" a certain point to get it started
Basically, it doesn't require you to fuss with it... just turn the dial and you're off.
