Narrative:

During climb out from dfw, first officer mentioned smelling an unusual odor. Captain smelled something only slightly. First officer called flight attendants to check ovens, galley, cabin for any odors or smoke/haze. They found nothing, but said they were using the ovens. A few mins later, first officer said smell seemed to be getting worse/stronger. Captain agreed and discussed with first officer that it could still be associated with the ovens. First officer called flight attendants to turn off ovens. This was done, but no apparent help. First officer said odor seemed to be progressively stronger and air around his instrument panel appeared hazy/smoky. Captain did not initially see this. We were near top of climb at this point. Shortly after top of climb, captain saw a puff of white smoke come out and down from just under first officer glare shield in front of first officer instrument panel. Both captain/first officer donned oxygen masks and smoke goggles immediately. Aircraft control xferred to first officer who then flew and communicated with ATC. Captain notified flight attendants of our conditions and decision to divert to iah, prepared cabin for landing and assess conditions in cabin/galley and report back. Ran all checklists during emergency descent toward iah. ATC provided initial heading, several frequency and altitude stepdowns/changes. So far, we did not have any abnormal indications in cockpit either on instrument or warning light or messages. Flight attendants reported ready for landing, cabin secure, no smoke, only odor in L1/R1, forward galley over and near ceiling in mid cabin. Captain briefed only possible emergency evacuate/evacuation upon landing, would notify via PA. Emergency equipment requested. Completed smoke/fire checklist with aircraft depressurization. Completed approach and landing checklist. Landing normal. Emergency equipment personnel inspected aircraft concentrating on cockpit/forward fuselage area -- nothing indicating fire. Captain and first officer decided safe to taxi to ramp/gate with emergency equipment following. At gate, passenger deplaned normally without further problems. Once passenger were off, captain and first officer opened cockpit window and left. Maintenance person was at cockpit door and asked electrical power remain on while he did checks. Maintenance stated that right forward windshield heat preliminary problems.
