Sounds far too relaxing, if normal alarms don't work I reckon you'll be blissfully unaware of this one doing anything!
A friend of mine has an alarm with motorised wheels on it. The idea is when you hit the snooze button, it falls on the floor and rolls around, gradually getting louder, so you have to get out of bed to go and find it to switch it off.
Don't know if it actually works though, she couldn't figure out how to set it..... :roll:
