Ring Alarm Clock- a ring on a ring

A vibrating ring you wear to bed, how can this not be good? Before you get ahead of yourself, Ring is a concept design by Meng Fandi, and I desperately hope a manufacture puts it into production soon.  Here’s the idea: the charging cradle allows you to set two separate alarms, one for each of the two rings.  Before you go to sleep, just slip a ring onto your finger and a silent vibrating alarm awakens you in the morning; perfect for the hearing impaired. 
The concept is also great for couples that have varying work schedules, or people like myself that don’t appreciate my girlfriend’s alarm blasting 3 hours early so that she can unconsciously slap snooze, which incidentally affords me one minute of sleep every nine minutes for the following 4 hours.  Of course, it’s then my fault I let her oversleep because that I didn’t realize she wasn’t conscious the 25 times she hit snooze; or when she yelled, “don’t touch me, I’m not in the mood!” Hopefully (for my sake) when someone does manufacture this incredibly awesome alarm clock, they’ll add a shock option for those stubborn sleepers. Unfortunately this device doesn’t work well for those punctual paraplegics; but what do they have that’s so pressing anyway?
