I don't if giving angry teenagers this kind of virtual dentist simulator would either interest ot calm them down but it seems that medecine-related simulators are a very thriving domain for VR/tangible computing specialist (as attested by the wonderful bovine palpation simulator). Look at this nice dentist simulator, they use "computerized dental dummies", it's developed by denx: Now let's think about this kind of interface could be hacked, tricked or modified: this wired driller could be a powerful controller for weird gaming purposes.
