SNMP Trap Alarm?

Ok, I could have picked a better title. I'm looking for a pointer to a box (pref. an embedded platform of some kind) that will receive/accept SNMP traps and sound a real world alarm/siren/klaxon. It can do fancy things like logging and such, but not strictly required. I could build one, but I'd rather have something OTS. Thanks in advance, Deepak
